DriVer.....I read your link and got a little lost in the amplifier issue. I tossed my switchbox years ago with the amplifier built in. Does the Jack antenna come with it's own amp?
As a side note: On my coach, there is an antenna up light on the dash that tells me when the Winegard crank up antenna is up. Since I don't use that antenna anymore, I tapped into the wire that indicates the antenna is up and connected it to my Winegard TravLer sat dish with a couple of contact switches. My dash light now tells me if the sat is up.
