I would like to use a pre-amp and coupler on a two antenna system, only one antenna needs amplification.
The Winegard manual says, "it is strongly reccommended that the power injector be installed between the pre-amp and combiner input".
So that means: antenna, pre-amp, power injector, then coupler- then insert/coax to TV?
Can I not put the power injector after the coupler (just before the TV), when using the Winegard coupler that has power pass on one port (7870)?
You can use the CC-7870 coupler between the preamplifier and the power supply. Be sure the preamplifier is connected to the set 1 side which is the power passive side.
