satalite connections

Hi folks,

I've got a question - I am running cable from sat dish (traveler three) under my slide out and up into the back of my entertainment center into an A/B switch. When I went to hook up the main line from the receiver to the A/B switch, I got a spark from the cable line. Could I have shorted something or is this ok?

    Every time you use that A/B switch you are going to get a similar arc across its contacts. This will shorten its life unless you unplug the receiver before switching antennas. If you are using a SWM system, you also need to unplug the power inserter. Once you switch antennas with the A/B switch, power everything back up and all is good. I learned this the hard way!

    That cable is a two way street. From the dish to the receiver it carries the television signal. From the receiver to the dish it carries power and instructions that the antenna needs.

    I don't think that's an issue? I've seen that spark when the two wires touch. Might be why my receiver (211)says make all connections before plugging in.
