I'm looking for suggestions for an OTA amplifier for the following situation: I have a SlimLine-5 dish feeding a SWM-8. The SWM-8 also accepts input of an OTA antenna. ~35' cable run. At this point, my OTA signal strengths are in the 80s-90s. This feeds a Zinwell SWS-8 8 way splitter which feeds a couple HD DVRs and a few OTA tuners. OTA signal strengths here are in the 30s-50s. One port from the SWS-8 runs ~20' to a Zinwell SWS-4 4 way splitter which feeds another HD DVR and a couple of OTA tuners. OTA signal strengths here are low enough that I've lost a few channels. So my questions are these: What would be the best OTA amplifier to use and where would it be inserted? Is there an amp that will amplify after the SWM and either pass the satellite signal unaltered or amplify it as well? Thanks in advance.
