Have only the UHF/VHF antenna connected and aim at about 190 degree magnetic compass direction.
Here is how to aim antennas , http://www.kyes.com/antenna/pointing/pointing.html.
Use a Old School magnetic compass to aim antenna/s.

If using both antennas.
Use a Winegard CC7870 transformer type isolation combiner to connect the 2 antennas.
The isloation type combiner reduces antenna cross talk and reduces signal bleed off of the 2 antennas connected to one coax.
And reduces the out of phase signals of the 2 antenna on 1 coax.

If using both antennas , aim the UHF/VHF antenna at about 211 degree magnetic compass direction and UHF antenna at about 138 degree magnetic compass direction. |
I actually returned the DB8 UHF antenna before I got around to reading this, but I have come across another antenna sold by Solid Signal called the HDB8X, which appears that you can aim two panels in two different directions and has high VHF capabilities.
I guess I'd like to know if these antennas actually perform like stated, or is it more gimmick than anything? Would I be better off with a basic directional UHF antenna pointed at 48 and my current antenna pointed at 10, 13, and 35, and use that CC7870 combiner? I'm trying not to break the bank here too. I've already invested 40 in a 10G202 preamp and another 65 in a CM7777 preamp. The CM7777 is pretty much useless to me as it kills any reception I had so I'll probably return that one.
My current setup is my old antenna pointed slightly West of due South. I don't have an exact degree, but there is one VERY small window that allows me to have 35 and 48 teetering on the receiving signal threshold. I am using the 10G202 preamp with FM trap IN. There is about 50ft of RG59 cable running from the preamp to inside the house. I then have a Radio Shack distribution amp with another FM trap IN and turned up all the way. I have tried the setup with a 4-way splitter instead of the distribution amp in hopes that less electronics in the mix would be better, but I actually do better with the amp inline. I am able to get around 75% on 10, 85% on 13, and 75% on 19 with this setup, but only 15-35% on 35 and 48. If I point right at 35 I can get around 50% and if I aim for 48 it will give me 75%. These numbers are estimates at best as I am using a signal bar on a converter box to test with.
