Since I had Voom installed with their Winegard batwing antenna I always get ABC and PBS. The ABC station I get is 50 miles away.
A few times I've gotten FOx and CBS to come in, and they're 71 and 73.9 miles away. Would it be worth my effort to try the XG91 with an amplifier? I'd probably also find a way to mount it higher, too, since the Winegard is on a low part of the roof of my guest house (only about 10' high).
Finally, if I did use the XG91 and an amp, could I use the diplexor supplied by Voom to power the amp? The diplexor is made by Winegard and is 12V. Or should I just run a separate line?
Mainly I'm just wondering if it's worth my while to even try to pull in these distant locals. I'd really love to get them, though.
Being the impatient person that I am, I went ahead and bought a 4228 yesterday with a 7777 amp. I mounted the antenna in the exact spot my batwing antenna was at, which isn't a good spot--it's only about 15' high and facing some trees. I also ran it through the diplexor instead of running a straight line.
Immediately I was able to pick up Fox from 73.9 miles away, and it hasn't went out since.
NBC and CBS would not show a picture until it got dark, and then they didn't go out at all. My signal strength (during the afternoon) would jump up well past 80 then all of a sudden down to around 40 for both. But as soon as it started to get dark, they stabilized and worked fine.
I'm also getting WB and UPN which are substations of my local CBS and Fox.
Tomorrow I'm going to actually mount the antenna on top of my house which is 2 stories and sits sort of on a hill. My backyard slopes and my guest house is pretty low, so this should improve things. ALso, I won't be shooting into the trees anymore.
THe only bad part is that it's going to be a very long run. I bought the mounting hardware for mounting it on the peek of my house and a 10' mast along with 200' of RG6. I'll now run a straight line and use the power supply that came with the CM7777 and bypass the diplexor to see if that helps.
1. Will having such a long run (maybe close to 200'; it's a long way to my guest house) affect signal strength.
2. If I wanted to split the line at some point and run it under my house so I could get OTA in my living room (I have a D* HD box), where would I put the power supply for the amp, and what kind of splitter would I use?
Ideally, I'd like to receive OTA in 3 places: 2 in the house and 1 in the guest house where I have my theater set up.
So far I'm pretty excited about the new antenna. No doubt it's a big improvement over the batwing, and I believe that mounting it higher and away from trees will improve things even more. It should be around 35' to 40' high once it's mounted since my house is pretty tall. I'm not looking foward to walking around on my roof since it's fairly steep but once it's all done I believe it'll be worth it.
