Hello. I bought two Winegard Two-Way HD Splitter for Cable TV Antenna Radio (SP-2052) here to supply my one cable from my two antennas to my basement where I a have my power inserter to power the two of the antennas and split to my two TVs. The antennas pick up an East signal and a South signal the way they are pointed and I have combined them after equal length 4 foot cables feed the first splitter down a 100 foot cable (all cable is RG 6) and to my power inserter for my Winegard LNA-200 amplifier. Then it is then split again to my two TVs. Most of my channels from the two antennas are coming in. I have two of the LNA-200s and one mounted on each mast as both directions need amplified (I am 60-70 miles from my towers). I am using two of the exact same antenna (Clearstream 4V antenna with the VHF adapter). Without using the first splitter by the antennas and running one at a time I receive stations great, but when I combine them I lose two stations from my East antenna (VHF-11 and VHF-13). I suspect that the extra splitter/preamp is causing too much loss of power for this setup and that is causing this problem (there isn’t any VHF-11/VHF-13 picked up on the South facing antenna at my distance from the towers).
I was at one point getting the two stations I lost though with this setup, but was messing around with some of the cables and lost them. Would it be best like in one of your diagrams that I saw to run only one preamp after the first splitter by the antenna? I had tried this at one point, but that didn't seem to work either. The only solution I can think of is to power each of the preamplifiers with a power inserter on each 4' to the antenna mast as you are supposed to power before you split. This would be possible because these antennas are in my attic.
Also, one thing I tried was a few different power inserters instead of the 5V/500mA that came with the preamps. I had read somewhere that I could try one with a higher amperage as that might help. Originally when I got this working I switched it for a 5V/1A power inserter and that is when it was working. I have since tried 5V/2A and 5V/2.4A to no avail. Same thing, I get everything but those two channels.
I know that some people will say just run two cables and use A/B switch, but I don't have co-channel problems and like I said it was working at one point in time. I just need to tweak if for permanent use. My zipcode is 17837.
