I have cut the chord and mounted a Digital antenna (Antennas Direct Clearstream 4) on a rod connected to my chimney stack so it is as high as I can get it. I get 3 of the 4 big stations and continue to struggle with adjusting it to get ABC (WJLA 7). I have raised the antenna as high as it can go, cut down tree limbs to clear the line of sight as best I can and I am at my wits end for ideas (and for today, patience). I don't have any kind of booster on the line (do I need something and if so, what?) and the cable length from dish to main television is about 50 feet or so. Any ideas?

Also, if I am considering hiring someone, do people even exist to help given I already have the antenna and am looking for some "fine tuning" services if I can't figure it out.

Thanks in advance.

To answer where we live, it is in Fairfax about a mile away from George Mason's main campus (south of it).

The C4 is a UHF antenna, it's fairly near-sighted on VHF, especially as the channel of the VHF station gets lower.

You could either try the C2V instead of the C4 or you could try adding the VHF upgrade kit which was intended for the original C2 antennas to your C4.

You are at a "paper clip antenna" distance from the transmitters, which are on Wiscomsin Ave, just before the Chevy Chase border. To be having trouble with channel 7 where you are, you are either down in a sinkhole or there is a Charles Smith building on your signal path.

I know this might not be easy to do if you only have a chimney mount at your disposal, but you probably could get better reception just by moving the antenna elsewhere on your roof. Sometimes, when someone is having a reception problem at a location where they should have gobs and gobs of signal, it is because there is a reflected signal also hitting their antenna that is unfortuitously out of phase with the direct path signal and largely nullifies it. It doesn't take much antenna position relocation to wind up with better results, though sometimes it might result in another of the reflected signals becoming problematic.

I live maybe five miles to the east of the towers and have a so-called clear line of sight to the DC towers, but I don't really have a clear line of site, because of vegetation, and my channel 4 comes and goes. I am in the commercial antenna business and carry more remedies on my truck than whomever you might call out does, but I am just too lazy to get up on my own roof and further experiment with the antenna because I have a second antenna pointed at Baltimore and can get NBC from there, so the only time I am inconvenienced by the channel 4 reception problem is when I am trying to watch reruns on CoziTV on 4.2, because there is no Baltimore CoziTV affiliate at present.

Ah, didn't see that you had listed your location. Do you get channel 7 at all, or does it go in & out? Any problems at all with channel 9? Do you receive 11 or 13 at all?

Short of augmenting your present antenna, you could try a Radio Shack FM trap anywhere in the line between the antenna & TV. You can return it if it doesn't help.

On a similar note, I tried to help someone in Merrifield a few months ago that couldn't get 7 even after trying 3 excellent VHF antennas. No matter what we tried, 7 proved to be a mystery even though 8, 9, 11 & 13 came in well. On the signal display, 7 would intermittently go in & out ever second or 2, proving some type of interference was present. We actually never found the source, but I still think it may have been the wireless sensors from the alarm system.
