For best reception of WCCU, the antenna should be aimed at WCCU. The cardboard covered with aluminum foil should be at least as large as the antenna and fairly close to the antenna to block WICD. The cardboard should be on the WICD side of the antenna. |

Thank you for the photo of your outside antenna; it looks like a Winegard HD-1080. http://forum.tvfool.com/attachment.p...3&d=1521744903 For best reception of WCCU, the antenna should be aimed at WCCU. The tree is not big enough to block the WICD signal. Quote:
The Winegard HD-1080 antenna isn't very directionaj. For best reception of WCCU the antenna needs to be more directional so that it will reject the WICD signal. If that isn't enough, a shield would need to be placed between the antenna and the WICD signal. For an outside antenna, the shield can be a wire mesh screen or a building that blocks the WICD signal, but doesn't block the WCCU signal. The coax must be grounded with a grounding block connected to the house electrical system ground to reject interference from WICD. http://forum.tvfool.com/attachment.p...1&d=1500059263 If even that isn't enough, you will need a custom channel 41 bandstop filter to make the WICD signal weaker. If that works, you will need another custom filter when WICD moves to channel 32: https://www.rabbitears.info/market.p...&callsign=wicd Just having one antenna isn't going to get all the channels you want. |
OK Thanks for the reply. The antenna is pointed approx 356 degrees magnetic (according to my phone compass) for WCCU, I'm hoping that's correct. I have plenty of guitar boxes approx 6'x5' I could tack this up on the rafters and let it hang down, cover with foil. I will also ground this antenna's coax splitter to the house panel. Will report back with my results, as soon as I get up in the attic!

Update: Without going into the attic yet, I put a new 4-way splitter with a built in ground block on the main coax coming off the attic antenna. Currently I only have the bedroom hooked up to this antenna, but eventually would want to add 3 more locations (all very close) Living room, dining room and another bedroom. I hooked up the ground screw to a #12 ground wire going to the main panel of the house. I saw NO issues on WCCU after doing this. HOWEVER I lost all channels on WAND 17 and WBUI 22. I took off the 4-way splitter and put on a 2-way with same ground and everything came back solid, no issues on any channels. I'm guessing I had a bad splitter OR is splitting 4-ways degrading the signal so much I'm loosing everything towards Decatur?

Your antenna is very directional. When it is aimed at WCCU, it doesn't pick up WAND and WBUI very well because they are in a different direction. That is why it is difficult to pick up everything you want with just one antenna. You should first work on your antenna system to get all the channels you want for just ONE TV, then you can add a distribution amp if necessary to compensate for the splitting loss. |
Rabbit73 I REALLY appreciate all your help! So, looks like I need a second antenna to go with the attic one? Should it go in the attic also? I could use the Winegard that's out in my yard, or there's a open box deal on a C2V at Best Buy for $35. Can I use a splitter in reverse to combine them? Or does it need to be a "combiner"? The UVSJ has been mentioned, but when I google it I'm not finding one. I'm concerned once I start adding TVs I'm going to have trouble, and the consensus seems to be NO AMP because of WICD being so close. This has been challenging but I'm making good progress. Thanks again for all your help!

This signal report from rabbitears.info shows the channels you want:

If you don't get all the channels after combining that you had when the antennas were separate, then combining with a splitter in reverse doesn't work for your location. Quote:
UVSJs (AKA UHF/VHF Diplexer) are getting hard to find. This is what they look like: https://www.antennasdirect.com/store...Combiners.html https://www.antennasdirect.com/cmss_...blyInstall.pdf http://forum.tvfool.com/attachment.p...1&d=1512355354 http://forum.tvfool.com/attachment.p...1&d=1497990764 https://www.radioshack.com/products/...itter-combiner http://forum.tvfool.com/attachment.p...9&d=1521912445 http://forum.tvfool.com/attachment.p...1&d=1497987173 Quote:
If you had a signal level meter, you could measure the strength of the signals, but you might have a TV with a relative signal strength indicator in the menu. With it, you could find out just how weak a signal can be and still be received. With the proper antennas, aimed in the correct direction, WCCU and the signals from the west should be strong enough. Once you have each antenna able to pick up the channels you want, then we can talk about the combining options. If the signals are still too weak after splitting, then a distribution amp can be added before the splitter. |
Thank you Rabbit73 for all your help. Odd occurrence this morning is all channels were coming in great EXCEPT WCCU from which we had no reception at all. Very strange. Lots of bad weather today, so that could be a factor. Thanks for all the combiner info! I will look at a winegard HD7694P

http://www.hdtvprimer.com/antennas/siting.html Scroll down to Trees and UHF if the hdtvprimer.com site is up. extract from that page: http://forum.tvfool.com/attachment.p...1&d=1493487319 Because the WCCU antenna is in the attic, you could try the suggestion by ADTech to add the Antennas Direct Juice preamp. That preamp resists overload as he said, but it might overload the TV tuner, in which case you could insert an inexpensive attenuator to prevent that. You also have a very strong local FM transmitter, WGNJ, also to the north, that might cause overload: http://www.fmfool.com/modeling/tmp/a...a/Radar-FM.png http://forum.tvfool.com/attachment.p...0&d=1521922105 Since the attic antenna also covers VHF, it will make the WGNJ FM signal even stronger. You could try inserting an FM filter in the coax between the antenna and the preamp input, but for some strange reason Antennas Direct has discontinued their FM filter and they were the only regular source left: https://www.antennasdirect.com/store...on_filter.html As a substitute, you can insert a UVSJ, UHF and common ports, which will pass only UHF signals and block VHF and FM. WCCU attic antenna > UVSJ > Juice preamp > coax > power inserter > TV This is an experiment; I can not offer a guarantee. |
Thanks for the link! And there aren't even any leaves on them yet!! :eek:

I wish I could give you some easy answers for your reception problem, but you have a difficult location. You will just have to continue with your antenna experiments to see what works, and in so doing you will learn a lot about OTA reception.
http://forum.tvfool.com/attachment.p...1&d=1521929155 Even if you had your antennas on a tower that was above the trees, you would still have a very strong WICD, channels in different directions, and FM interference to deal with. A custom channel 41 bandstop filter to make WICD weaker from Tin Lee Electronics would probably cost over $100. http://www.tinlee.com/MATV-Bandstops.php?active=3 You would have to call them and talk with one of their filter engineers and send your TVFool signal report. PAR Electronics might be able to make one for less: http://www.parelectronics.com/single-channel-tv.php The least expensive filter would be from Jan Jenca in Slovakia. They sell on eBay. http://www.antenne-komponenty.eu/eng...ct/filtre.html http://forum.tvfool.com/attachment.p...1&d=1477099490 They also sell combiners, and could make one for Fox on real channel 26 that would allow you to add it to the other channels before splitting. http://www.antenne-komponenty.eu/eng...zlucovace.html http://forum.tvfool.com/attachment.p...1&d=1482191285 |
UPDATE: I purchased the Winegard 7694p as suggested by Rabbit73 (thank you) and put it on the tripod in the back yard. Pointed towards WCCU 360 magnetic I was still getting intermittent pixel distortion. Nothing on WAND or WBUI to the West from Decatur. I went out and swung the antenna towards the West about 260 magnetic and now I've got EVERYTHING...21 channels, and WCCU is so far coming in flawlessly. I know the leaves are not on the trees yet, but somehow all channels were very clear last night and this morning. I'm just hooked up to my bedroom TV with quite a bit more RG6 than I need (it's running to the living room then back, prob about 100' or so) so I assume the next step would be just leave the attic antenna out of it and start splitting to my 3 other TVs? :confused:

Thanks for the report; your test results are encouraging. Keep experimenting to see what works.

Here's my latest update. I turned my attic antenna back towards the south west like I did the new 7694 antenna in the back yard, and bingo! All the channels came in perfect. So now I am splitting the attic antenna for my son's bedroom and the dining room. Then I'm splitting the backyard antenna for my master bedroom and living room. Right now, it's all working perfect. Some nights I'm pulling in other channels Charleston when I do a new scan. Don't know what will happen when the trees leaf out, but right now it's working great. Thanks for all the help here. I just started a new thread on my commercial building in Downtown Champaign.
