Can anyone recommend a good brand of diplexer for FTA and OTA used together? I have some "perfect vision" diplexers I'm using and one of my OTA channels gets lost in the process. I'm hoping maybe a different brand might fix this.
Thanks

What channel (callsign, city) gets lost?
Go to TV Fool and input your city/state, then get a listing of the channels available.It's an ABC channel 19 WXOW out of LaCrescent, MN
I just bought a set of "Holland" STVC type and they work great (perfect), another brand I tried acted as a short and my receivers didn't boot up.

How strong and what direction is the one you seek?
Perhaps it's weak, or in a different direction from the others you receive?
There is some loss in diplexers, which is why I don't use them.
If you absolutely must, maybe a better antenna or a small amplifier would help, prior to sending the sig to the diplexer on the roof.
Channel 48 UHF is not near the edge of the passband for the diplexers: 674-680 Mhz
Can you use a diplexer and still run a positioning motor?
My Coolsat and Pansat stbs are feeding motorized signals through the diplexers then through a 4x1 switch to seperate DG380 motors... yes you can use a diplexer and still run a motor or several motors.
I reconfigured my motor dish setup as I mentioned earlier, I'm mixing fixed dishes with my motor feeding through the "Holland" STVC diplexers and it's working perfectly. I did have a circular LNBF hugging the Linear LNBF on my motor dish for ION TV on 119.o°W using a 22KHz switch, the Linear was on the "22KHz on" port and the circular on the "off" port. Everything worked fine except for the circular feed, the motor seemed to wonder back and forth in the vicinity of the 119 sat as if it was looking for it, occassionally grabbing the signal as it passed it up. So I removed the circular LNBF and the tone switch, all else is just fine. I haven't figured out why the circular feed was confused, maybe another day when I have time.
I never had any luck using a 22Khz switch after the motor in the setup you described, would always screw up for some reason. I changed out the 22Khz switch for an SW21 switch and it works just fine.
Here is what I am currently running on one of my setups; From the stb through Phillips Diplexers that combine my OTA and sat signals, then to a Chieta 4x1, port one to a DG380 motor driving a 1.2 meter dish then to a DMX242 LNBF, port 2 to a DG280 motor driving a 76cm dish then to an SW21 switch, port 1 of the SW21 to the Linear port of an Invacom QPH-031 and port 2 of the SW21 to the circular port.
If you ever figure out why the 22Khz switch doesn't work please let me know, I haven't figured that one out yet.
Well, it turns out my wiring was to blame. The people who wired the house used cheap twist on f connectors behind the wall plate and didn't ground them properly. Now I can get my OTA and Satellite fine.
