#4 - FEEDLINE
This antenna is designed for use
with 50 Ohm coaxial cable termi-
nated with a PL-259 connector.
Any length of feedline can be
used with your A144-20T. The
shortest length of cable will have
the least loss. Two connector boots are
included for use with your new antenna. Slide the
boot over the cable before attaching your PL-259 (figure
F). Spread silicone on the outer threads of the Reddi-Match and
PL-259 connector. DO NOT COAT THE CENTER PINS OF THE PL-
259. Attach the connector to the Reddi-Match. Apply the remaining silicone
to the outside of the connector. Slip the vinyl boot over the connector and
against the mast bracket for a weather tight connection. Use electrical tape to
secure coax to boom and mast as shown in Figure F.
