WebThe “Bullet” End Fed Antenna Matcher. The key to end fed antenna success is the matching network interface between the long wire antenna and the coax feed line and feed line … WebThe tower must look electrically solid. 2.At the base of the tower, carefully open the jacket of the coax feeding the beam and solder a small bonding wire to the coax shield, waterproof the cut, and bond to the base of the tower. Also, bypass the rotator cable wires with .005 or .01 at 1kV caps to a bonding wire to the base.
