You may be getting multi path from the different lengths of wire after your splitter. I would consider getting rid of the CM 7777 and using a 2 way splitter amp. The idea of the LTE filter may work. How far are you from cell towers?

Thanks Jim, not sure if I can reply here. I've been put on notice by DrDon.
I've tried this setup without the CM7777 and its worse on all channels.
The splitter is post amp.
Multipath is a term the station engineer mentioned about the signal bouncing off objects (hills, ground, trees,etc) and arriving at the antenna at different times and the tv processor has trouble deciding which one is real.
He said that is usually the cause of the "signal" meter jumping around.
That is why he is recommending a more directional antenna with a narrow beam width. The 7694 is 46 degrees on channel 50.

I'm less than a mile from a cell tower.

Since I will need a new antenna when WISC from 50 to 11, I was hoping for a recommendation or confirmation of what the station engineer said.

If you are less than a mile, I would start with the LTE filter. I still recommend using an amp, I would just try one that splits the signal (think CM 3410). Make sure you put the LTE filter in ahead of the CM 7777 or any amp.

The LTE signal is probably getting over modulated in the amp. Another thing you can try is a 6ft length of coax for instead of 3ft on the TV that works. I know is sounds counter intuitive, but it is worth a try.

Thanks again Jim.
My engineer guy suggested the CM3201 filter before the preamp at the antenna so it gets removed before amplification.
https://www.channelmaster.com/TV_Ant..._p/cm-3201.htm
I don't know how the connection can be made with this to the CM7777 preamp on the mast and be kept weather proof?


Do you or anyone else have any experience with this filter?

It will screw into you input on the CM 7777. It is meant to be weatherproof. Shouldn't be a problem. Use a weather boot on the filter input or some silicone. Amazon sells coax weatherproof boots for the bottom or input. Crutchfield has the instruction sheet for the LTE filter on their website.

Awesome Thanks, I'll give it a try before replacing the antenna to see what I get.

Another quick question: I'm planning on getting a Wingard HD7694P this spring because my trouble channel WISC V3 real 50 is moving to real 11 in September. I currently have just the front (yagi) UHF section of an old combo unit installed going to the UHF input port of the my CM7777.
I plan to put the Cell filter on the UHF side of the CM7777 to see what that does.

Looking at the HD7694P install manual, it shows a sort of combiner box (circuit board) where a single down lead coax is attached.
My CM7777 is the older version with separate UHF and VHF inputs.
Can I even use the HD7694P if it combines the signals on the antenna with my amp?

Thanks,
Dan

Yes, you need to open the box, there will be a small switch that needs to be set to combined input.

Yes it does...I believe the UHF input says combined on the unit. It may have worn off with the weather. It looks like this.

Quick update, installed the LTE filter and made sure the FM trap was in along with the UHF / combo switch.
I also ended up about 8 feet shorter on the mast. My mast is telescoping 1.5 inch conduit up the end of my house and I always needed to Put a step ladder on the peak to pull the pin to lower it and service the amp or antenna.
I decided I am too old and maybe wiser for that so I took out a section at the ground and now can lower and service the antenna standing on the roof.
Anyway I'm not sure if it was the filter or the lowering but now I have a solid 80-90% on my tv signal meter where it bounced between 35 and 55 before. There is no pixilation or drops ever now.
All the channels seem to have bumped up in strength.
Very happy with the results.

I still will need to replace the antenna UHF with a combination unit when WISC goes from 50 to 11 in September.
Has anyone tried the Wingard HD7694P they would be willing to recommend or not?

Thanks for the help and advice Jim,

Dan

If the UHF portion works fine you could add a VHF only antenna like the Stellar Labs 30-2475.

https://www.newark.com/stellar-labs/...vhf/dp/48Y8141

I have the big brother (30-2476) and it works great. I need it due to distance from the tower

27-1 looks like crap now and they are going to bit-starve it even more. Idiots.

Anybody else having issues with WZCK 8? Seems I'm getting a signal but my TiVo states "problem with signal on this channel". Similar story on my other TV using a different antenna setup. No issues with 23 and 38 which operate off the same tower. Also periodically 8 will come in just fine, seemingly no correlation with skip, wind, etc. Know that they had transmitter issues earlier in the year too, wonder if its related.

Not that it's the most important channel in the lineup but I do enjoy popping The Office on in the evenings I have off, also appreciate the variety you can get with the antenna these days, hope to see it stick around.

Madison Area DTV Channel Reallocations

WISC has been announcing on a scroll they will be implementing their planned broadcast frequency move to VHF 11 on 10/18.

Based on TV Answers (https://www.tvanswers.org) the following stations are expected to move their broadcast frequencies as part of the digital spectrum reallocation apparently on that same date. I had only known about WISC's move before. If any of this is incorrect or if I'm not reading the information correctly, then please post corrections.

Station: WIFS - Independent 57
Market: Madison, WI
*Timeframe: Phase 6: September 7, 2019 - October 18, 2019
The station's Wikipedia page says they will move from UHF 32 to UHF 21

Station: WISC-TV - CBS 3 CBS
Market: Madison, WI
*Timeframe: Phase 6: September 7, 2019 - October 18, 2019
Move from UHF 50 to VHF 11

Station: WMSN-TV - FOX 47 FOX
Market: Madison, WI
Rescan Day: October 18, 2019
The station's Wikipedia page says they will move from UHF 49 to UHF 18

I haven't seen any work being done on the tower regarding the changes for WISC and WMSN. Both stations need new antennas and waveguides.

you should look again....



WISC's new aux line and antenna have been going up over the last week and a half... We are going to our Aux starting tomorrow on ch 18... WISC and WMSN are set to switch at 10am, WIFS moves to candelabra to combine with WHA... they change to ch 21 at midnight or 1 or 2... I don't remember.

top antennas probably coming down next week with new ones going up... then WMSN/WISC lines being replaced.

Explains why I haven't seen anything. I do not keep a constant eye on the tower, nor do I use a telescope to get a closer look. I've been mostly paying attention to the antennas on the top. Now I know the sequence. Thanks for the update.

Strange that WIFS is moving towers. They should be able to use their current amtenna, that they combine with WMTV. A lot of money was spent on the tower and transmission building/transmitter. Can they move the current transmitter over to the new location's building, or did they have to buy a new one?

I'm assuming that reduced power will be used by the stations, if not turn off completely, while workers are on top working on the antennas.

New transmitter for WIFS when they do the top stuff, we'll all be on our aux with lower power, lower on the tower... we'll be off for the few hours they will be working in the aperatures doing the transmission lines. the just are putting up the false bracing section for the gin pole now ... I think they take down WHA/WISC Analog post/beacon off first, then put up the new WHA/WIFS antenna... re-rig to the other leg, then take down the WMSN/WISC UHF antennas... then put the new ones back up... beacon is moving over to that stack

Low Power Stations Frequency Reassignments

Based on info at the FCC, it appears 2 of the Madison low power stations will at some point move to new broadcast frequencies if they stay on the air. Rabbitears.info and tvanswers.org don't yet show these. Tvanswers.org seems to indicate they might move but no deadline has been set. Please post any corrections if I've got it wrong.

WZCK-LD, virtual channel 8
Currently on UHF 36 and I believe has been assigned UHF 24.

WMWD-LD, virtual channel 38
Was on UHF 38 and apparently not broadcasting at this time. I believe has been assigned UHF 15.

So am I correct in assuming that WISC channel 3 Madison isn’t at full power yet?

Correct. In addition to operating at reduced power, they are also transmitting from an antenna only halfway up the Madison Community Tower, which also reduces their coverage.

Looks like things are a bit behind schedule as the tower crew was 6 weeks late getting here after their last job ran long. Latest update from WISC is that they expect work to be completed by December 9, maybe by mid November.

These articles from the State Journal and Cap Times have a lot of detail on what's going on:
https://madison.com/wsj/news/local/d...fd878f757.html
https://madison.com/ct/news/local/ci...ea9d89d17.html

I feel for the local station engineers having to deal with all the angry calls from people who don't know how to rescan their TVs. And the uninformed experts who are sure this all down to the local stations not having planned:

Quote:
“Clearly they didn’t do what management is supposed to do before undertaking a major project, which is to foresee all eventualities,” Doherty said. “It was obviously out of their control before the project got underway.”
If only we could all be perfect like Jim Doherty from Spring Green.

Oh well.

Reception's been fine for me with my rooftop antenna on near west side of Madison.
