Santa Claus brought me a new King Controls, Jack antenna to replace my old, leaky bat wing. The installation seems to be pretty straight forward, and She (Santa Claus, that is) has ordered the optional mounting plate, which will cover the old bat wing mounting holes and make for a cleaner installation.
The question I have, for anyone who is familiar with this product, is in regard to the "wall mount power injector)" a small, plate mounted electronic device that is included with the kit. Is this device necessary to the operation of the antenna, or is it an option that enhances the performance, but is not strictly necessary for operation? Anybody know?
I'm only asking because it will require a fair amount of extra work to run the power and coax to this thing, to get it mounted in a place convenient to the location of the TV. If it is necessary, or even worth the extra trouble, I will do it, but I will leave this part out if it is only going to provide marginal improvement of reception.
Thanks.

The antenna has an internal amplifier which is powered down the coax just like the Winegard ones. You need it.

While we are talking about over the air TV antennas. I recently replaced my omnidirectional Wineguard roadstar antenna with a much smaller Majestic omnidirectional antenna it has a 30 db gain and it does pull in more distant stations. Also it does matter where it is mounted. The Majestic doesn't work as well on the aluminum roof as it does on the fiberglass end caps. I found the best performance with it mounted on the rear a/c unit as the original du therm units had a plastic pan rather then metal.

I have the Jack Antenna. And, yes, it needs the amplifier. Without it, the reception is not nearly what it should be. With everything hooked up and working, my Jack antenna works as well or maybe slightly better than the "bat wing" (and I had the HD extender on the bat wing).

I also have one and have been pleased with it's ability to pull in stations and the fact that it can easily be rotated if desired. Also, not having to remember to wind the antenna down before driving off made it an ideal choice for my coach. Mine is mounted in the middle of the coach and I mounted the little box just above the refrigerator. It was pretty easy to snake the coax that far.

Okay, thanks for all the info and suggestions, guys. I'll get it figured out. I have changed the location of the TV from where the PO had it and he had it wired for cable, satellite, and air (batwing), so I'll have to improvise.

If you are wiring the amplified Jack antenna, or any other antenna that uses a 12v power injector to supply 12v to an internal RF amplifier into existing TV wiring in the coach. (I know that my English Teacher would hate this sentence fragment).
You need to inspect your TV outlets that were mounted in the coach. Some of the outlets have the RF amplifier built into them. I have one Wingard that is made like this. Two amplifiers in series will not improve your TV reception.
