Denny - Your TV antenna mast mount pre-amplifiers --- How are preamplifiers powered ? --- I don't see any easy way to get 120VAC up to an antenna if they are AC powered.
Thanks, Paul

Paul, TV antenna Preamplifiers are two part units. The mast mounted preamplifier and the indoor power injector. The power injector is located indoors and requires an electrical outlet. The coax cable down lead from the mast mounted preamplifier feeds into and out of the indoor power injector. The power injector converts the 120V to low voltage DC in sends it up the coax cable to supply the preamplifier its power to operate. The mast mounted preamplifier receives its power via the coax cable from the power supply. Signal splitters should not be installed between the mast mounted preamplifier and the power injector.
