Put it on a rotator and watch your neighbors' eyes pop out as the antenna spins around. You might even be able to get some stations from Connecticut that way.

Most of the poor results on Low band are on channels 2-3. Once the analogs are turned off, the maximum low band power can be raised.

Channels - CM4228 performance
14--: The CM4228 is excellent for channels 14 and higher (UHF).
7-13: For channels 7-13 it works, but only if the station is nearby (less than 30 miles).
2-6: For channels 2-6 you need a VHF antenna like a Yagi boom. For me, I have channel 6 in Philadelphia, but since it's a lousy station, I decided to lose it.

How did you connect your YA-1713 and 4228 together? A VHF/UHF splitter cable?

Why can't the 4228 get all the stations like my rabbit ears do? Ok my rabbit ear is really 2 atennas, two scoping and one round

By way of a VHF/UHF diplexer, such as:

I am considering another one to filter out Low-VHF as I have no need for those frequencies.

The 4228 is one UHF antenna, which happens to work for some upper VHF channels. Don't expect anything out of the 4228 for channels 2-6 and possibly 8 and 12.

I do not have 8 and 12 available in my area. Can someone confirm the performance of the 4228 on these? HDTV Primer shows nulls for 8 and 12, but I have not been able to test these as I am in an "odd channel" DMA.

The other answer is that the 4228 is quite directional, meaning stations coming from the sides or the back aren't as likely to be received unless the antenna is turned.

I've never heard of anyone being able to subscribe to the locals alone from Dish with having to have one of their packages - the cheapest one being the Family Tier, which will run $25.00 w/locals (you do get a fairly nice selection with that package, though - better than anyone else's Family Tier, in my opinion). Cable's your only option for that from a provider.

You may not even have to get all the way up on the roof with an antenna. On the wall, a lower eave, or even just in a pole or tripod on the ground will usually be a big improvement over indoors. Something like the 4228 would just hang flat on a wall and might work, provided you don't have any stucco, aluminum siding, metal pipes or foil-backed insulation on or in the wall in that spot.

I can get channels 7 and 8 pretty good on my 4228. Analog channel 7 is about 30 miles out, and analog channel 8 is about 98 miles out. It's an encouraging sign for me that the upper VHF works so well with this antenna since some of my local UHF channels are moving to high VHF channels come 2/17/09. Should be interesting to see if it performs as well with digital upper VHF.

Side reception is no good. It will pick up signal from the back though, provided it's strong enough.

I have THREE 4228's. I love this antenna.

Note: I recommend guying any mast it's mounted to (all mine are guyed).
post #44 of 170
Can I get my antenna girled instead? I prefer girls. ;-)

DishTV offers locals for either $5.00 when combined with another package, or else $6.00 when purchased alone. I've already talked to a phone rep, and she confirmed I would only need to pay $6 if I want my seven local stations. However the dish/box would be sold separately, unless DishTV is running a "free equipment" special.

Rather than waste a lot of money & crawling around on a roof trying to install an antenna, I might just take this $6 a month deal. Or the $19 Comcast deal. It depends on my mood.

You answered your own question. You have two separate antennas... one for VHF (rabbit ears) and one for UHF (loop). The 4228 is only one antenna: UHF.

And yes the 4228 also works on VHF-hi, but merely by coincidence not design. I can get channels 8, 10, 11, 12, 13 Analog on mine. No idea how digital performs, but I'm hoping it's good, because I have several digital stations on VHF post-2009:
8 - lancaster
10 - harrisburg
11 - baltimore
12 - philadelphia
13 - baltimore

So I'll either have success, or I'll be adding a 7-13 VHF Yagi to supplement the 4228, or I'll be watching channel 8 and nothing else. In retrospect I probably should have bought a UHF/VHF combo antenna, but it's too late now.

Thanks for the info. I've been told in my area(55337) that only one station will use the VHF high, none that I'm aware of will use VHF low.

Two stations KMSP 9 and KARE 11 will be going back to their VHF legacy channels in Feb. 09 - correct on the no low VHF

Do your have a TV with a QAM tuner? You might get lucky with the $19 Comcast plan and get some free HDTV channels.

What hardware will in need to run 5 tv's off this antenna

I bought a mast mount preamp from lowes for the immediate gratification. I also asked the HDTVprimer engineer if he thought I should buy a "better" preamp in my quest for WNBC-DT (46.5 miles away). He said don't bother.

The Lowe's preamp is 300 ohm in so it takes the output of the 4228 with just a straight twinlead.

I've got about 50' feet of RG6 and a 1:2 splitter feeding a Dish DVR and an Avermedia PCIe combo tuner. The splitter "looks quality" on the outside and it has ext that sstates it's good for UHF.

Nor can it pick up WNBC-DT from 46.5 miles east of the ESB. Even mounted on a 10 foot pole, on top of a 1.5 story house.

Doubt it. I've had the 2-15 channel plan in the past, and they install a low-pass filter that blocks everything above channel 16.

Thanks, I just saw the chart on our local forum today. It looks like 2 indeed. At least their both in the upper VHF band. The 4228 should work nicely, unless you're a long way out.

Question - for you or anyone else who knows for sure:

I know this isn't recommended, but will the Channel Master or any other distribution amps pass the power from a mast pre-amp?

The reason I ask is, when I added one split to my setup last fall, I lost just enough signal on some channels to make the reception of them spottier. I know I can just replace the antenna with one with more gain (which I probably will do anyway), but I would still like to split the signal in the house at the TV a couple more ways for other reasons.

A passive splitter won't cut it, even if I replace the antenna.

Essentially they can't. But you can place the power injector for the pre-amp on the upstream side of the distribution amp.

One other possible solution that I'm considering myself is that if you have any uneven splits, to use a tap instead of a splitter. So if you've got, e.g. a two way split which goes to one TV on one side, and a four-way splitter with two TVs and two DVRs on the other, put in a 12dB tap instead of a splitter.

(In my case I have the antenna going through the basement to a distribution point for the rest of the house, but there's one TV in the basement which is split off in the basement. Perfect candidate for a tap, but since the setup works anyway, I haven't bothered)
post #56 of 170
Would it be possible to use the tap at one TV after the injector without replacing the two way, power-passing splitter under the house?
post #57 of 170
Depending on how your house is built, you may be able to use the 4228 in the attic. I mounted mine upside down from the highest point in the attic, I used an extension pole with two clamps to a rafter, tight enough to hold it, loose enough so that I could turn it. Had no problems, rock solid signal from 30+ miles with no amplification driving about 40 feet of RG6.

I'm really confused on how to run the cables. This house was built long time ago and just can't see how to do it though the walls. How do the cable people do this and with the Amp it has to be near a power plug. one good thing is we took the ceiling tiles off the basement ceiling so it's open.
post #59 of 170
I am 35 miles from post-transition rf 8 and 10 behind a small (50 feet wide) cluster of too tall trees and in an itty bitty valley (ground gradually slopes up 100 feet over one-quarter mile). TVFool has all my stations at pink or better. If I get this antenna 35 feet above ground, is it realistic that I can pick up these VHF stations with the 4228? Has anyone had any luck picking up channel 8 -- the stats I've seen don't look that hot at that frequency.

There have been a lot of posts saying that hi-band VHF reception with a 4228 is decent, even though it was designed as a UHF-only antenna. I'd like to konw if anyone has had any luck getting channel 8 who might have similar obstructions as I do. I'm not expecting miracles from this, trust me!
