If you are going to replace the BATWING on its crank up arm just pull the two pins and place the Kings antenna in its place.
Just use the same RG cable you was using for the BATWING. The JACK antenna Internal Pre-amplifier will be powered up by the same 12VDC the BATWIG antenna was using. The Kings Jack antenna will be pointing to the transmitting TV station to the RIGHT in this photo..

If your Kings Jack is the low profile install you will have to remove the whole BATWING crank-up assy. The Jack antenna in this case will not be very high and will only rotate.

I was not impressed with the JACK ANTENNA all that much as compared with Vanguard BATWING with dipoles. I got better performance with this antenna on my setup...
