The only channels I'm really interested in getting are: 9, 10, 48, 35, 20, 43 which are all at 159 degrees.
Currently I have an antenna at about 20 feet up. It is one with 4 bow-ties on two panels, Antenna's direct DB4e . I have a small yagi antenna mounted above that to get channels 9 and 10. They go into a signal combiner and then into a pre-amp (originally a CM 7777 but now a Wineguard boost xt-20) then 60 feet of RG-6 into a splitter that goes to the TV and to a HD Homerun tuner.
It worked quite well for 6 years. Occasionally channel 9 would drop out but mostly they all came in decently. But just the other evening I lost all channels. When I checked the HD Homerun signal strength it showed 100% on signal strength but around 55 on quality. Then it would drop to 30 on quality and then lose all signal. Then it would repeat. I thought maybe the signal was over-amped with the CM 7777 so I swapped in the boost-xt (out on the ladder at 10 PM in the dark) and all the channels came back.
I thought everything was great until the next evening around 7 when channels 9 and 35 would drop out and then come back after awhile over and over again. I'm not sure if the signal with the lower amp just isn't enough for those two now. I don't have any tall trees closer than a half mile away and even then there aren't many but I was wondering about trying to raise the antennas a foot or two. Or if it would be better, since all the channels I want are in the same direction, to switch to an antenna like a CM-2018.
It looks like channel 9 may always have issues with being a slightly weaker signal and having another channel 9 coming from the other direction but 35 looks like it should be decently strong.
Suggestions are greatly appreciated.
