Shorting Stubs Used as a UVSJ

I understand enough to know that being 1/4 wavelength (for two different wavelengths) is important, but beyond that it's just .




Winegard UHF Tetrapole Stub Function

from Winegard Patent US3,518,693

The dipole 12 differs from the conventional folded dipole in that the upper dipole arms 12a are not continuous but split to form separate inboard ends. However, with the feeder stubs 20 mounted at the inboard ends of the upper dipole arms 12a as previously described, a low impedance, or R-F short, is presented across these ends at frequencies within the UHF frequency band. As a result, driven element 12 serves as a folded dipole in the conventional sense for this frequency range with signals being fed across the gap at the inboard ends of dipole arms 12a without any substantial effect.

At frequencies below the UHF range, however, the R-F short between dipole arms 12a is no longer present and a high impedance (open circuit) is effected. With this result it will be understood that the antenna constructed in accordance with the present invention will operate effectively on frequencies within the UHF band and at the same time permit signals within the VHF band or other frequencies from a separate antenna structure to be coupled to the inboard ends of dipole arms 12a, and therethrough to the terminal connection points 12d to the down lead T.

No adverse effect is encountered for either the signals in the VHF or UHF bands and signals in both bands are coupled to but one down line without an intervening coupling apparatus being required.

End of Patent Description





Shorting stubs are used in place of a UVSJ in a combo antenna for convenience and low cost. They are not quite as effective as a real UVSJ filter, because a stub is only a short for one frequency. Two pairs of wide stubs cover UHF fairly well.

The GE 34792 contains a real UVSJ filter:







The GE 29884 is the outdoor version:





Attachment 2 shows what happens to the UHF Polar Pattern if you do not use some kind of isolation network like a UVSJ or shorting stubs to remove the UHF signals received by the VHF section of a combo antenna.

Good antenna with built in amp but plastic build quality may be a concern outdoors. Great for attic. Currently on sale Amazon for $119 with $17.90 discount coupon.

Also Winegard Flatwave Air on sale Amazon for $67.98. Good outdoor flat panel antenna also perform very good with built in amp. But maybe not quite as good a Elite model for VHF because it lack VHF dipole.

But I still like Antop 400BV flat panel antenna with VHF dipole. Come with inline amp but excels if you add external preamp instead. Has indoor stand or can be used attic or outdoors.

Winegard Elite 7550 appears to be a 4-Bay Dipole Antenna (similar to W-G HD-4400)...PLUS a pair of (apparently Unconnected) UHF Resonator Rods at Top and Bottom....PLUS a Hi-VHF Dipole (likely 0 dBd = 2.2 dBi, give or take some Combining Loss????):
http://www.winegard.com/help/images/c/cd/2452393.pdf
http://www.winegard.com/elite

"We're the NEW Winegard....we no longer NEED to provide any Stinking SPECS!!!!" However, Azimuthal Pattern Chart indicates either 8-10 dBi OR 8-10 dBd = 10.2-12.2 dBi in UHF Band....they didn't stipulate, but I suspect it's the latter, higher numbers.

Clearly someone chose to use a "Pretty"....but WAY TOO SMALL Reflector System....which explains why HD-4400 4-Bay Dipole with 4 Reflector Rods has significantly higher Gain = 12.7 to 15.1 dBi:
https://imageevent.com/holl_ands/mul...winegardhd4400

================================================== ============
HDB-4X is a REAL 4-Bay Bowtie Antenna from Solid Signal at 1/3 the cost:

Unfortunately Winegard no longer makes their 4400 and 8800 UHF antennas. 4bay and 8bay versions. They were good antennas. But I guess they are now going for cosmetic and aesthetic appeal.

I have had an 8800 since before the digital transition. It still works well. I am thinking of replacing it since the last time I checked it, it had some rust on it, and one of the whiskers seem to be loose. Birds keep landing on them.


The 8800 has to be aimed very tightly on the station you want too. Turning it just an inch can mean no signal or a good signal for weaker stations. I have been very pleased with it over the years. I think it is much better than the 4400.

I used to service the cut-to-channel VHF antennas on a highrise building where the elements kept breaking off. The manager told me that it was because of the birds and I thought, "Yeah, sure", but what I didn't realize until I saw it was that they'd have a dozen birds light on the elements, and when the wind would blow, they would act like sails and develop enough force to bend and eventually break off the elements.

I have a tv antenna hooked to six boxes in my house and a channel master (ota) dvr. Things are working good in that department. I am wondering about setting up a cellular antenna. I called ATT, and they told me to use wifi for cell calls in my house. They were not very helpful in giving information about cellular antennas. I see some antennas online that say they will manage 5g when it completely rolls out. I am not sure about what is needed besides the antenna.

Any thoughts?

Exactly what are you trying to do? You can't just plug an outside antenna into a cell phone. There is a such thing as a cell phone booster that can work quite well if set up properly.

I saw this on Amazon. It looks interesting.

https://boltontechnical.com/bolton-t...ional-antenna/

The cellular signal in my house is weak. A couple of miles from my house I get a 5g lte signal on my iPhone XS. I started thinking "what about a cellular antenna" and whatever else goes with it. I have seen people using cellular antennas in remote areas when I am camping. Those antennas seem to work with varying degrees of effectiveness.

I saw that antenna on Amazon; that seems like a good start. However I am a bit stymied by the cell phone boosters I have looked at online. It seems too early to look for a 5g booster, but 4g might be cost effective. I would like not to spend $500 on a booster, especially when I know that 5g is coming. I was wondering if someone on this thread has experience with the antennas and the boosters, and might head me in the right direction.

The advice I got from ATT was to use the internet for cellular calling. Ok - that works, but I would like to experiment with OTA cellular at my house, and maybe end up putting something on my RV, car and/or boat. It's really just a bit of fun.

I had a cell phone booster (WeBoost) at my previous location and it worked great. That antenna is only an antenna. You still need the booster. The booster is a little tricky to get working right. The indoor and outdoor antennas need to be far enough apart and not pointing at each other so there's no interference.

I wouldn't be buying anything in anticipation of 5G at this point. If you have poor cell coverage now I wouldn't expect 5G to be better... probably worse.

I've yet to install one, but I've done a decent amount of research on cell boosters. Like others have said, you want to ensure that the antennas are far enough apart so the system doesn't start "ringing."

I'd go with WeBoost or Wilson products - they both make products that cover most all of the band currently used for 4G/LTE. Directional yagis, pairs of directional yagis and proper aim are important. https://www.cellmapper.net/ can help you out, although a spectrum analyzer would also be invaluable.

Re 5G: Keep in mind it will operate at much higher frequencies and will thus require different (luckily smaller) antennas. Also keep in mind there will likely be more 5G cell sites than 4G cell towers, with each 5G site covering a smaller area. 5G transceivers may be placed on street lamps or something similar; the 5G frequencies are much more "line-of-sight" than 4G and less able to diffract around small obstacles.

FYI: Each Carrier has exclusive channels assigned within particular Frequency Bands used for 4G/LTE (voice & medium speed Data = 10 to 25 Mbps)....but some might not be supported in any given location....and some Bands might not be supported in older phones...and new Bands [with wider Bandwidths as well as higher 5G Data Rates] are expected to come on-line "soonish":
https://en.wikipedia.org/wiki/AT%26T...quency_summary

Note that Band Numbers correspond to different assignments within each Band. 700 MHz Band has longest Range, but usually lowest data rate due to narrower Bandwidth.

FYI: Thus far, prototype 5G [oftentimes it's not quite "real" 5G] are inner city micro/nano-cells for trial runs. In suburbs many microcells would need to be installed on [many/most/all???] lamp posts....IF that ever happens (5G via LEO SAT is coming....soonish).

So a 4G/LTE Booster is specific to a particular Carrier....and SOME support multiple Carriers, just in case you might want to change Carriers.

You should talk to local suppliers of Boosters [in addition to AT&T] to make SURE that a particular model will do what you WANT....and they will also know which way to point the outdoor antenna when they install it. For DIY/Amazon, it's risky, cuz you're on your own......

Just a few examples so you know what sort of AT&T Boosters are available...and one company's evaluations:
https://www.repeaterstore.com/pages/...ignal-boosters

https://www.amazon.com/Booster-Ampli.../dp/B07NWDDMDT [Only AT&T, 700 MHz in Bands 12/17]

https://www.amazon.com/T-Mobile-Ampl.../dp/B07RS26SRL [Only AT&T + T-Mobile, 700 MHz in Bands 12/17]

No. Even if you were to use a proper feed it is too small to provide much gain. A yagi is better.

I assume you mean, "can the dish be converted into a reflector for a cell phone antenna?"

A: Today's cell service frequencies are too low for such a small dish to do you any good. But once 5G becomes a thing, it might work as a reflector for a 5G antenna.

As for your second question, RG 6 cable works up to around 2 GHz, so it should work with most current cell service frequencies. But 5G will require something different.

So: use the cable now; save the dish for later.

Question Cary, NC - High House & Maynard - Get Rid of Rotor?

I currently have an ancient Winegard 8200 on the roof and cheap (at the time) Chanel Master rotor. I have grown tired of having to twist the rotor for every different channel. It gets out of calibration easily and is balky in cold weather. I have been using a compromise fixed location but now that the repack is happening this is no longer working. Most of my desired stations are either ESE or WNW.

I was considering a Clearstream 4Max but it is kind of spendy at $150+ for a 4 bay bowtie sans reflector and a single high VHF dipole. The nice thing about the 4max and this location is that it is bi-directional at the cost of gain, which it looks like I probably don't need.

The repack is removing 11 and adding 8 & 9 on high VHF. which may be an issue for the 4max and its reduced gain.

What are your thoughts? Any alternatives?

So, what are your 'must have' stations? What are your 'would like to have' stations?

Unfortunately, TVFool isn't being updated with latest info, i.e. strong WRAZ (PBS on Ch40) and WRDC (MYN on Ch28) are flat out MIA...and the UHF Channel Assignments for 6 UHF Stations have changed.

After determining your approx Street Address (to 0.1-mi accuracy of your TVFool Report), I ran fol. Current TVStudy Report:
https://www.rabbitears.info/search.p...pe=dBm&height=

Currently, [non-rotating] Hi-VHF Dipole Antenna pointed towards middle of 99-125 deg (rel True North), "should" receive WTVD (ABC on Ch11) and WAUG (??? on Ch8).

And in the "near" future [must complete Re-Pack Phase 9 by 1May2010], WNCN (CBS on Ch17) will move to Ch8 (towards 123-deg), WTVD (ABC on Ch11) will move to Ch9 (also 123-deg). And in the "opposite" directions, WTNC (Univision on Ch19) will move to Ch11 (330-deg) and WIRP (??? on Ch22) will move to Ch11 (280-deg)....although for the last, a simple Dipole may or may NOT be inadequate, depending on Man Made Noise Level, trees/terrain and other factors....

FYI: Post Re-Pack assignment changes are very extensive, but fortunately they all stay in the New Ch14-36 UHF Band, except for WNCN, WTNC and WIRP mentioned above, see fol:
https://www.rabbitears.info/search.p...pe=dBm&height=

Note that fol. stations will either shut down or sign Channel sharing agreements with other stations: WRTD (IND on Ch49), WRAY (REL on Ch25), WLXI (IND on Ch25) and WRAL (TeST) on Ch39. Also note that WAUG (??? on Ch8) moves to Lo-VHF Ch4...so fergitabout it unless you keep HD8200 permanently pointed towards 99-deg (more or less).

With an outdoor C4Max, you "should" be able to receive all UHF Stations [towards Networks at about 123-deg] with "Signal Margin" greater than 20 dB....and perhaps down to at least 10 dB. And it would be worth trying it without the reflector if you want stations in "opposite" directions, bearing in mind that there are still NULLS to the sides.

You didn't say how many receiver drops you need, so we can discuss PreAmp/DistroAmp alternatives....acknowledging that you have Very Strong FM Stations, whose 2nd Harmonics can interfere with Hi-VHF Channels:

The 4 max is not a 4 bay bowtie it is a 4 bay loop antenna.

The "ultimate antenna" Danny Hodges sells on Ebay
would be a excellent choice for your location.
Simply install it without the reflector and it should give excellent results for only $85 bucks.

I can personally vouge for the 4228, a very good value. It has very similar gain specs (for what that's worth) to those claimed by the DB8.

Actually the 4228 is a superior design.
It doesn't suffer the added loss of coax jumpers,
an additional balun, and a combiner, it merely uses just one balun.

http://www.winegard.com/elite

"We're the NEW Winegard....we no longer NEED to provide any Stinking SPECS!!!!" However, Azimuthal Pattern Chart indicates either 8-10 dBi OR 8-10 dBd = 10.2-12.2 dBi in UHF Band....they didn't stipulate, but I suspect it's the latter, higher numbers.

Clearly someone chose to use a "Pretty"....but WAY TOO SMALL Reflector System....which explains why HD-4400 4-Bay Dipole with 4 Reflector Rods has significantly higher Gain = 12.7 to 15.1 dBi:
https://imageevent.com/holl_ands/mul...winegardhd4400

================================================== ============
HDB-4X is a REAL 4-Bay Bowtie Antenna from Solid Signal at 1/3 the cost:
https://www.amazon.com/Xtreme-Signal.../dp/B00CX6QBIO
Also CM4221HD at 1/3 the cost:
https://www.amazon.com/Channel-Maste.../dp/B000FVTPX2
Or A-D DB-4e Re-Optimized for current 470-698 MHz Band:
https://www.amazon.com/Element-Bowti.../dp/B0074H3IU6

Plus your CHOICE of a VHF Antenna, such as:
https://www.amazon.com/Antennas-Dire.../dp/B00LHFRCMG [Universal VHF Dipole Kit incl VHF/UHF Combiner, $25 with Prime S/H]

Or, if you need more than a simple Dipole for Ch7-13, either of the fol. Hi-VHF Antennas:
https://www.amazon.com/30-2475-Fring.../dp/B014M0XXES
https://www.amazon.com/30-2476-Fring.../dp/B07R69QJ3Q
Where VHF/UHF Combiner is extra:
https://www.amazon.com/Masthead-Ante.../dp/B015ZSVDAW [DC PASS on UHF Port]
After trying a DB4E, 4221, and a Stellar Labs 4 bay bowtie, i went back to my Winegard 4400.
......
The John Winegard phased fat dipole design produced a wider beamwidth while still providing greater or equal gain on my desired channels.
.....
If Winegard decided to bring a modern 14-36 version of the 4400 to market, they would dominate
the uhf antenna market.

UHF signals are line of sight only and cover poorly in hilly and mountainous terrain so vhf signals will always be used in those areas.
VHF also travels much further and is not effected by trees nearly as much as UHF frequencies.
