When watching and recording TV, I'm getting choppy images and sound on most channels despite signal strengths that I thought would be strong enough. The Problem gets worse on windy days. Because there is so much signal strength fluctuation in all the problem channels, I'm wondering if I'm having multi-path issues? I would greatly appreciate any help you can share. Thanks. This table link combines the TV Fool signal data with 3 more columns at the end that show the results I'm getting. I can't see any pattern that explains why only channels 9 and 12 are consistently good. My setup: Someone gave me a large used roof antenna including mast, but it's currently installed inside my attic without the mast. It's aimed at 240 degrees based on Iphone compass, and is around 20' off ground. It has a lot of close wood contact because its surrounded/weaved into my attic trusses. All cables are new quad-shielded RG6 cable. Cables run from antenna to a 2-way splitter. Line 1 goes to TV ROAMIO OTA, then HDMI cable to TV. Antenna Line 2 goes straight into a TV in another room, which gets better reception than the TIVO set up.

There is also one large tree beside my house at 110 on compass, and my antenna is now on the opposite side of the house from that tree. Which should I try next? Should I try a different compass setting. (If I re-positioned it in the middle between the attic trusses to get it away from the wood, I would have to point it either 102 or 296.) If I should try an attenuator, what db #? If I must mount the antenna on the roof, I could, but I would prefer to avoid it if possible. Are there other options? I already had this TA-25 amplifier. I just tried it, and it didn't help at all.
