I don't have a signal number, but only a bar meter. But I would say that I got a 10 to 15% improvement with the XG91 over the Silver sensor I have. But the Silver sensor has a little Zenith amp on it and a very short, maybe 8 ft cable. I tried the same amp on the 4228, it pushed performance past what I had on the XG, but I didn't use the amp on the XG. I'm also using exactly 100 ft of RG6 cable from walmart (hanging out the window for now
), would I be better off getting some other cable?
I would say that the XG with no amp, for me is about 5% better than the 4228 with no amp. And the 4228 was about 5 to 10% better with the amp, so I think the 7777 will prolly make a BIG difference!
Also my tuner is built in the TV(32 inch Sanyo), I have nothing to compare it to but I think it does ok.
I did lock in WUNF 33 asheville with the 4228 and amp, but not with the XG. Can't quite get WLOS 13, but I think its real close.
What finally got me to get another outside antenna was that I started not being able to get WVLT consistently, and was starting to have problems with WTNZ.
