TV antenna amplifier replacement

Is there 12 volts DC getting to the switch?
It could be blown fuse in DC panel or in the back of the unit.
I would not replace just the coil replace the complete power supply.

agreed.. The 1st question is do you have 12V coming in ?

Changing that choke (coil) is a last resort, but if you have an ohm meter, pull the power supply plate out and do continuity checks from the input to the switch, through the choke, etc., and see where the loss is.

Not sure if it could apply here, but one thing I have run into a couple times is that the coax going to the roof antenna that is supposed to carry the 12v was screwed onto an "un-powered" stub in the Winegard splitter back behind the Winegard panel instead of onto the one that is "powered."

I replaced my old antenna with a King HD TV antenna, but could not get it to work. After troubleshooting it, I found that the amplifier was dead. What should I replace it with?
I was thinking of the Winegard Sensar Pro. Is that a good choice?

The Sensar Pro is an excellent unit.... I have one and love it.

Now; one fault: you said "The amplifier is dead"... You tossed the amp in the trash with the rest of the old Batwing,, What you have inside is only a power supply and switich (At least in most cases)

The Sensar Pro, however *IS* an amplifier, as well as a power supply for the "Mast head" amp (Same as the old wall plate) and a switch, and a scanner, and a signal meter and... well you get the idea.. Very nice and handy

My apologies, the wall unit power supply is dead, the antenna (with built in amplifier) is new.
