Have you considered networked tuners? They're the ultimate multiple-antenna integration if you have, or are willing to run some Ethernet instead of coax cables. For as much as a quality electric coax switch costs you could buy one. Although you would need two.

I had two very nice Radio Shack switches, but they got lost in a forced move. I call them vertical switches because they were designed to be mounted on a vertical surface:



I bought a switch that looks like this switch on eBay because it looked like the RS switch; it works well:



I also bought 2 of these, but I haven't tested them yet:

This 75 ohm relay would ground the signal output of the VHF preamp power inserter when the main antenna is being used. The 50 ohm CX230 BNC relay doesn't.

Many thanks, rabbit. I ordered one of the RS ones and will have a look at the others. The vertical orientation is good as I moved the switch point into the media closet so I don't have to make trips to the attic just to flip a switch. Why I didn't do that years ago anyway, I don't know.

I use a HDHR tuner, but it's just for RE scans. Maybe I should consider using it for IPTV in the house. Is that what you are thinking? Can I get SmartTV's to talk to them? (I hope so)

Here's a picture of my RF switching. My six antennas each feed distribution amplifiers and then separate feeds go to switches where I have inputs for three TVs and my HDHR receivers. I can select any antenna to any receiver with a push go a button.

Very nice. Thank you, Larry and good to talk to you again.

This is something I can aspire to and maybe I should get more of the push button switches. The slide switches are quite poor as noted about and it seems you agree.

Here's my current media cabinet setup, but it didn't look like this 24 hours ago. I need to reconnect and clean it up. And yeah, I need to keep it wife-friendly as well.

Exactly, a networked tuner allows you to completely optimize and automate (DVR recordings) even in the face of complications like dual antennae to receive two transmitter locations, without resorting to technically-compromised approaches like RF combining. Or even the inconvenience of an antenna switch your recorder can't operate.


Most smartTVs can access a DLNA source, which the tuners are. The most advanced implementation of networked tuners will connect a tuner to each antenna, then run a media server on the network . This could be a PC, but "appliances" that serve this purpose exist, think of it as a super-DVR. I use Emby on a PC, but there are others. The media server will "combine" the dual tuners seamlessly to appear as a single live TV source, it can even include cable TV. In the configuration page for the HDHR you configure which channels are received on which antenna, the wife and kids don't even need to understand which antenna they're using. They just tune the desired channel.



I should mention the "advanced implementation" of networked tuners using a media server is not that difficult for a moderately tech-savvy user. Otherwise networked tuners can be dead simple for the tech-challenged using DLNA.


Edit: forgot to mention SiliconDust is releasing their ATSC 3.0 tuner next month, a feature some of us can take advantage of now or very soon.

http://www.askacom.com/


They don't list the UV-SJ or specs on their website, but it is in p. 9 of their catalog and available for sale by some resellers. Probably discontinued like everything else VHF pre-repack when everybody thought VHF was dead.


I think I'm going to grab one while they're still available. The UVSJ is going to be under the eaves of the house, not up on the pole, so no big deal to access if for some reason I'm not happy with the performance.

While I appreciate the hit of RF steam-punk nostalgia, you can buy a lot of state-of-the-art consumer HDTV receiver from SiliconDust with the benefit of ma$$ production pricing. It solves the antenna switch problem, the DVR and Wife Acceptance Factor (WAF) problem, ATSC 3.0 upgrade problem, and probably world hunger as well.


Once you add a second antenna you just can't beat the networked tuner.

My error; I thought you only had one coax line coming down from the attic. If you have two coax lines, you don't need an electronic switch; a mechanical switch will do just fine.

Bingo! Well, I've had that media closet long before we were married and the re-design of the closet. Thankfully, she's very tolerant and understanding of my RF looniness.

Alright. I need to get on that then and yep I am a backer of that 3.0 tuner. It will be a good time to finally figure out DLNA stuff.

For what it's worth....

I have a Synology DS1817 connected via 10gbe to a netgear switch that has two 10gbe ports and my desktop (Ryzen 2700x/Quadro P2000) runs Plex server and also has a 10gbe network card. I have a separate 5 port 1gbe switch that the two HDHR quattros are plugged into. Each HDHR has an Antenna's Direct "UVSJ" to combine UHF and VHF antennas up on my mast. I keep the Plex metadata on an old enterprise grade Intel 600gb SSD and also use that drive as a "scratch disk" since it is fast and has just stupid write endurance.

In other news, Ch9 WSWP is still very unpredictable for performance. I haven't really messed with the setup any as I intend to get an RTLSDR and then see what I can learn from that. As such, can multipath be "seen" with an RTLSDR?

Nice network setup. I just upgraded to 10Gb optical as well. It's overkill, except for those large file movements over the network.


You can see multipath by demodulationg the OFDM signal and looking at the error vector magnitude (EVM), particularly as it changes with multipath conditions. Something your tuner reports as signal quality, usually in percent. A spectrum analyzer (a bit generous of a term for the RTLSDR) would usually break up EVM into phase and magnitude error, possibly giving you a bit more insight into the signal problem.


One of the key characteristics of multipath is it's variability, and I suspect the phase error might be worse than the magnitude error, but I don't know for sure. You can probably confirm multipath well enough with a good tuner if you're just looking to fix your TV reception. But if you want to experiment, sure, RTLSDR.

Antenna mast chimney mount

I thought I had the mast chimney mount figured out: Concrete anchor into my pre-cast concrete chimney using these Penninger Radio PMB-200 mounts. I'm fortunate to have a sturdy concrete chimney instead of brick, and will be running two each 2" X 8' X 1/8" wall thickness sections of antenna mast and a mast joiner clamp (I went for overkill with the MC-200-12). I'm going to take advantage of the strong chimney and masts, pushing the unsupported length to 12' above the chimney to mount two UHF X-beam antennae and a full-band Winegard HD5030 VHF. So I need some space around that VHV on the bottom.



Then a contractor friend of mine told me he would never put concrete anchors into a chimney. Although this isn't crumbly brick, but pre-cast concrete. I have considered that high-strength epoxied-in 1/4-20" threaded rod would be pretty darn strong. But now he has me second guessing myself on the attachment method.


I have seen the corner-mount chimney straps described as heavy duty simply by using 4 straps instead of two. But they only accept 1-1/2" mast, although I'm sure I could modify them (X 4, what a PITA!?!) to accept 2" mast buy installing 2" U-bolts through drilled holes in the bracket.


What would you do? Trust the 1969 concrete chimney won't be weakened by epoxied anchors, or try to make a strap mount work, X4?

Are there any good smaller outdoor antennas worth buying ? I just need high VHF and UHF. The antenna towers are 29 miles from my house. I have a large Winegard Yagi antenna I have to move, and a smaller antenna would be much easier to mount on the side of my house. At antennaweb.org the channels we watch show up as red and blue.

Thanks for any advice.

Thanks for any advice.

Please read the stickies at the top before asking antenna questions. We have no idea what your antenna requirements might be. Post a link to your Rabbitears report. What antenna do you have now? People have completely different ideas as to what a "large antenna" is.

Okay, taking my cue from what you recently said. Do it the right way, not the easy way.

Two sections of Rohn 25 with an eave bracket will hold your 2" mast nicely. It's also easy to work on. I only use towers these days unless it's a very small antenna.

I'm going to take advantage of the strong chimney and masts, pushing the unsupported length to 12' above the chimney to mount two UHF X-beam antennae and a full-band Winegard HD5030 VHF. So I need some space around that VHV on the bottom.



Then a contractor friend of mine told me he would never put concrete anchors into a chimney. Although this isn't crumbly brick, but pre-cast concrete. I have considered that high-strength epoxied-in 1/4-20" threaded rod would be pretty darn strong. But now he has me second guessing myself on the attachment method.


I have seen the corner-mount chimney straps described as heavy duty simply by using 4 straps instead of two. But they only accept 1-1/2" mast, although I'm sure I could modify them (X 4, what a PITA!?!) to accept 2" mast buy installing 2" U-bolts through drilled holes in the bracket.


What would you do? Trust the 1969 concrete chimney won't be weakened by epoxied anchors, or try to make a strap mount work, X4?



Just in case
I made this mount to clamp around my chimney.
All pieces I bought at my local Lowes.
I bought the largest alltread to fit the holes (1/2").
I even bought my tv pole mounts & 10ft conduit pole there.

Nice setup, I see you brought your antennae with you when you moved. While your point is well taken, the chimney has an abundance of structural strength. It is really a matter of suitable attachment. The eave sides of my house a tower would interfere with my camper, or would be in the middle of the sidewalk. There are other locations for an unsupported tower, but the chimney is more than strong enough to do it the right way.

I think you're right with the clamp approach. No relying on concrete anchors or wobbly corner brackets. The point load of the brackets is distributed across the entire chimney. It would be only a bit of fabrication, good idea.

There are two types of multipath, static and dynamic. I will cover static first.

Notches in a scan of the channel might indicate a multipath problem, sometimes not. It depends upon the shape of the signal when the RTL-SDR scanner software crosses that channel.

Channel 13 in my avatar to the left was multipath with an indoor antenna. The signal was strong enough, but the image was frozen; too many errors. This is the TV screen that was at the same time:



I moved the antenna to the center of the bedroom in a high traffic area (of course); the reception was excellent:





It is also possible to have a flat scan but the tuner can't decode the signal. When Trip in VA was living in Chattanooga, he had an unusual multipath problem:

I did a side-by-side on WSB and WDSI because WSB decodes and WDSI does not.

Trip's solution was to put the antenna in a trash can which narrowed the acceptance angle of the antenna and rejected out-of-phase reflections.

A possible explanation for a flat scan when there is nultipath is given by Dr. Bendov in his paper DTV Coverage and Service Prediction, Measurement and Performance Indices:
Quote:

page 4
VIII. SNR AND “FIELD STRENGTH” MEASUREMENT VIA SPECTRUM INTEGRATION

Defining the Signal as the total received power and the Noise as AWGN (Additive White Gaussian Noise) leads to the conclusion that the SNR at the input to the receiver increases with increased multipath.

In urban and indoor situations, there may not even be a main signal, only reflections, some of which are of equal magnitude.

If all multipath signals are part of the signal power, then the SNR margin may not be an indicative figure of merit of reception robustness. In any case, even accurate measurement of the total received power may not be trivial.

The integrated signal power is not just the Desired Signal power. It includes, Man-made, Galactic, and thermal noises and residual transmitter generated in-band noise. It also includes some but not necessarily all multipath signals. For example, pairs of identical and asymmetric echoes, one of positive amplitude and positive delay relative to the main signal and one of negative amplitude and negative delay relative to the main signal, will cause only a second-order distortion of the displayed power spectrum. They will create group delay. Thus, in a multipath channel, a pair of such echoes would measure high SNR when using the spectrum integration technique whereas in reality, the true SNR would be much lower.

There may be other combinations of echoes that would yield essentially flat spectrum display.

Using "Kindorf" for a chimney mount is an interesting solution. I probably would have turned the channel around so the flat side was on the chimney and used the t-nuts designed for the channel to actually attach the mast.

Personally, I'm a huge fan of "epoxy" (two part adhesive) based masonry anchors. Specifically Wej-It Power-Sert stainless steel anchors.

On our house, I used SteelTek "lego" in 1-1/4" (sold at Lowes) and some big structural screws to install a mast to the structure of the house. In hindsight, lagging Kindorf to the house might have been a better solution for the house to mast connection so I could have adjusted the position of the mast on the house or take it down but leave the hard point on the wall of the house.

That trashcan antenna shield reminds me that I need to download that antenna simulator software and see if I can't figure out a potential plan for a larger reflector on the big VHF.

Dynamic multipath can be caused by moving vehicles, aircraft, or swaying tree branches in the signal path.

Yesterday was windy, so I did some newbie videos of channel 16 with my old Canon point-and-shoot digital camera:

https://www.dropbox.com/s/8gsw9t1zsr...Path2.mp4?dl=0

https://www.dropbox.com/s/ig3va499k237ayu/CH16TreeInPath4.mp4?dl=0

Channel 16 reception was stable in spite of the wind; it had a high SNR.





The VHF-High channels didn't do as well. They were strong enough, but their SNR was reduced by a higher noise level.

I'm heading back up to Washington tomorrow with the 608 MHz LTE filter, which I hope will help with the apparent overload problem on UHF. I'm also taking a VHF bowtie with me to see how it does. VHF is super noisy in the attic. I know, I know...

Here are the signals up there.

https://www.rabbitears.info/searchma...study_id=93095

And here are my current attic results with a DB4e (actually a DB8e but I only put up half on the early Feb trip) and only part of the Stellar VHF Yagi (not in a good spot). The attic is much like most modern home attics. Filled with insulation and framing and hard to move around in.

https://m.rabbitears.info/index.php?...T&unit=&auto=Y

If I don't get the results I want this time, it will be time to do what you have all been telling me in July (get it outside!)

We all know outside is better. An XB16A (or XB10A if less gain is required) X-beam antenna will introduce additional "filtering" of LTE as the gain curve starts to roll off around 600MHz. Whether this is a solution for you I couldn't say.

One of these? XB16A (Group A)

https://www.aerialsandtv.com/knowled...rmance-reports

Been there and done that. I didn't find it much better than anything here in the US. So I gave it away. And shipping wasn't cheap from the UK. I've tested the new LTE filter here in SoCal and I think it will do well. We'll see.
