OTA Problems

[clayj]

I have a new SWM-8 installation, and am having problems with the OTA signal. I have an OTA antenna connected to the SWM, and then from the SWM things go as follows:

SWM-1 -> 30' of coax -> diplexer -> HR20 (one side to the SWM Satellite port, the other to the OTA antenna port - each about 2' of coax)

SWM-2 -> 60' of coax -> SWM Splitter
SWM Splitter Port 1 -> 10' of coax ->Toshiba HDTV (just using the OTA signal until I can scrape up the cash for another IRD or DVR)
SWM Splitter Port 2 -> 30' of coax -> diplexer
diplexer port 1 -> Samsung HDTV (OTA only)
diplexer port 2 -> HR21 SWM port (there is no OTA port on an HR21)

If I terminate diplexer port 1 in a 50Ohm resistor, everything works great (except no OTA on the Samsung, of course). If I connect that second cable to the Samsung, the HR21 'locks up' (video freeze, or white screen on a power cycle).

The HR20 works fine.

Over on the DirecTV forum, they're now saying "this won't work"

Anyone here have any thoughts?

Thanks in advance!

Have you tried swapping diplexers to rule out any issue with that specific part? We have not encountered a bad one, but it's worth a try.

Also, we have a more expensive diplexer that typically isn't required, but if you want to try it, let us know by email.
