Need help in Denver
(this is the second time I've submitted this post; the first hasn't appeared)
Here in Denver all the major stations have their transmitters on a mountain west of the city, just 16 miles from us. We get great reception for all but two of these stations, KCNC 4.1 and KDVR 31.1, despite their transmitters being located near the others. Oddly, however, they are the ONLY two stations we can receive with a cheap, flat, indoor antenna; why are they the only two we can't get with the outdoor antenna, a Winegard 7694P recommended here? It's mounted at least 25 high and pointed toward the transmitters; we have just two TVs and no amplifiers. We have run the channel set-up on both TVs several times. Here's our signal report: http://www.tvfool.com/?option=com_wr...90383df73b2a07 Thanks for any help... |
Mike,
There could be any number of issues at play. The outdoor antenna could be overloading the tuners on KCNC and KDVR. This could cause the issues you are having. Did you "walk" the outdoor antenna on your roof before deciding where to mount? TV and radio signals often take different paths even when the transmitters are emanating from the same point. I would try re-positioning the outdoor antenna. Try moving up/down on the mast, try pointing a bit north/south of the transmitters. Remove the antenna from the mast and "walk" the roof with the antenna in hand. Someone will need to be watching your tv/signal meter. Are there trees between you and the transmitters? You may need to go above the tree line. The Winegard 7694P IS a good antenna and a good choice for your area. I'm certain others will come up with many other possible issues for you to address. Good Luck! |
I vote for tuner overload. The solution is to attenuate the signal. Here is one supplier with them in stock. You may need as much as 9 dB attenuation, so buy three 3 dB attenuators and use as many as you need.

Thanks for the suggestions; we are limited to exactly one place where an outdoor antenna can be mounted (on the chimney) but it can be raised or lowered a bit, and turned. I'll try repointing the antenna first. If attenuators are needed, are they placed (in series) in the incoming cable upstream from the splitter?
