#5 - FEEDLINE ASSEMBLY
Before attaching the feedline permanently, tune the antenna as outlined
on page 2. The antenna is designed for use with 50 Ohm coaxial cable
terminated with a PL-259 connector. Any length of feedline can be used
with your A50-3S. The shortest length of cable will have the least loss.
A connector boot is included for use with your new antenna. (Figure F)
Slide the boot over the cable before attaching your PL-259. Coat only
the outside connector threads and shell with silicone grease.
Do not
coat the center pin or receptacle. After the PL-259 is firmly screwed on
to the antenna connector, slide the vinyl boot over the connector and
against the mast bracket. When taping the feedline to the mast it's a
good idea to form a drip loop in the coax to help protect the connector
from water damage (figure G).
