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,
Jim
