    A month or so ago, I was having all kinds of problems with the satellite signal randomly dropping in and out and the DirecTV installer narrowed it down to the SWM-8 I had installed years ago.

    We had a thunderstorm the other day and were having signal issues, so I switched over to my off-air channels and noticed I have all kinds of pixellation and other weird problems. Off-air signals are unwatchable. However, signal strength test shows the signal is coming in quite well.

    So, I took a look at my SWM and discovered the installer had replaced the 15' long piece of coax I had spooled up and connected between my Power Injector and my SWM-8. I believe a minimum distance of 15' was the rule when the SWM hit the market. I now have a shorty 18" or so piece of cable, since I had installed the PI about a foot away from the SWM.

    Thus the question: Has anything changed relative to SWM-8 installations? Has the minimum distance between the PI and SWM-8 been reduced?

    I have no idea if this may be the cause of my OTA issues, but things worked great with the installation I did many moons ago.

    if you are using the SWM1/PWR port for power, then the 15 ft is recommended. however, you can connect the "shorty" to the legacy 3 port to provide power to the dish with no limitation in cable length

    If there is a splitter between the PI and SWM1/PWR, it doesn't need to be 15'.

    Thanks, VOS. Haven't been on here in a while and glad to see you are still here helping the masses.

    The original install (which I did) had a cable from the PI to SWM1/PWR. The DTV install replaced my 15' cable with a shorty and made the same connection, not a connection to Legacy 3. I had a feeling I'd have to put my 15' cable back.

    why not connect to legacy 3 if they are together?
