The antenna is in the attic due to higher winds at my location. I did find one end that is suspect that I'll need to replace this evening (need to buy a tool to replace with). I'm also intending to replace the pole that I've mounted to to a PVC pipe instead of the metal pole that I used.
You don't really need such a large antenna. A Winegard HD 76xxP series antenna mounted on the roof would be your best bet in my opinion. I'd go with the 7698 or 7697, but one of the smaller ones should work well for most of your stations if you desire a very compact antenna.
3 & 6 are gettable UHF stations, but even the best VHF antenna would have a tough time getting 8 reliably. You may be better off with a roof mounted UHF only antenna since Fox 8 is iffy at best. The 91-XG is probably your best bet for UHF only. (Very low wind drag, & only 6 pounds) A less expensive alternative would be the Winegard 9032.
So an antenna like the 91-XG with a channel listing (High gain across entire UHF band (UHF channels 14-69)) Should be able to pick up down to 3.1 and 6.1? That is where I guess I'm confused with the antenna selections......
Ok. I've replaced the suspect end ( the center wire was bent ) and eliminated the preamp from the equation. So far I can still only pick up 10.1 and 47.1. I'll see if I can get ahold of 91-XG or something like it to see if my fortunes change.
Several stations under 7 miles? Have you tried a paperclip? Bend it into an "L" and insert it into the antenna jack. While I can only get one channel that way, it like most of my digitals is between 25-30 miles away, Antennaweb recommends a red zone antenna. Can you try your antenna in the living room on the floor with different cable? I strongly agree with the cabling assessment, as well as going without the amp.
I'm going to move the antenna to the roof (from the attic) to see if that helps. I really don't want to have to buy a new antenna if I don't have to. As far as the cabling goes, it goes straight from the balun on the antenna to the tuner on the TV (about 150' of RG6 cable).
