.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.
Paul, TV antenna Preamplifier's 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 electricity to low voltage DC inserts it into the coax cable and sends it up the cable to supply the preamplifier operating power.
The answer is, the mast mounted preamplifier receives its power via the coax cable from the indoor power injector. Signal splitters should not be installed in line between the mast mounted preamplifier and the power injector unless voltage blocks are in use.. Proper preamplifier installation is crucial but quite simple.
