Your best solution is going to be to run a line just for OTA.JimTed said:I purchased a SWM8 from Dave29 (great transaction and very helpful) and had the unit installed yesterday. The SWM8 seems to be working fine with Directv signals and is operating (2) HR21s and (1) HR10 with strong signals.
A non-amplified antenna used for digital HD over-the-air was wired into the SWM8 off-air input and then diplexed out at the two HR21 locations (1 into AM21 and 1 into HDTV tuner). In this configuration, the antenna signal is suffering significant loss and some channels (PBS) can not be tuned and others (ABC) have signal loss problems (pixelating). When the antenna is wired directly into the AM21 the signal is great (almost 100% on the HR21/AM21 meter). I tried using a Channel Plus DA-550 HHR before the SWM8 OTA input but this only provided slight improvements.
Any suggestions from the community on a cost effective fix to this problem? Pre-amp or amplify the antenna signal and still wire through the SWM8 and diplexers? Pre-amp or amp the antenna signal but run separate RG6 feeds to the antenna locations? I already have the wiring set up to bypass the SWM8, but I am not sure the right right pre-amp/amp to purchase.
Thanks for any suggestions,
The built in diplexer in the SWM8 is not "top of the line"
So, if you insist on diplexing, best to use an external diplexer to bring in your OTA, then of course one to break it back out at the receiver.
From there you can start fiddling around with amps/pre-amps.
Also keep in mind that diplexing is not approved or supported by DirecTv with the SWM units (despite it being built in, wouldn't surprise me to see it removed on a later revision), your on your own support wise.
