General Description The Penetrator is a full-size 5/8 wave, omnidirectional antenna. A full-sized radiator with a lower radiation angle concentrates power closer to the ground. It can be fed by any standard 50 ohm coaxial cable such as RG-8/U and RG-58/U. For runs over 50 feet, RG-8/U RG-213/U is recommended.

The base assembly will have the top Place one of the radial brackets on the insulator pre-installed. Remove the three base and align the holes so that the 1/4-20 nuts, bolts and split washers. bracket is square with the base. #8 self taping Place the other bracket on top of the first and align the holes.
