The reason it does not work when you use the cable inlet is the amp is not the amp it's a swich and power inserter.. The Amp is in the Over the Air antenna head. not in the wall.
The Sat receiver supplies one of two DC voltages to the LNB in the antenna. also some signal info.. And all of that can NOT pass through the winegard switch.
"
So you have two options..
You can access the back of the Winegard wall plate disconnect the park cable *(I think that is the center connector) and extend it to the receiver.. I do not like to do this for multiple reasons.
Option 2 is run a nice new RG-6 (Get it at any Hardware, Lowes, Home Depot) from the receiver to any handy hole in the body (like next to a water pipe for example) and out to a compartment wheere you either store a coiled cable (Not my first choice) or use a double female (Barrel) connector or mount a connection box.
Or alternatively drill a hole and install a bulkhead fitting properly sealed
And unplug the receiver (or otherwise remove AC power) Before connecting or disconnecting antenna. Just for safety. RG-6 quality stuff, all the way from Receiver LNB port to antenna if you please.
WHY. Well. losses, 6 has about 1/4 the loss of 59
Home was where I park it. but alas the.
2005 Damon Intruder 377 Alas declared a total loss
