( ) When assembling the antenna, the Driven Element must be slightly
modified to complete the antenna tuning. Do this by adjusting each side
of the Driven Element to 106-3/8" from center of boom to tip of element.
( ) Install the beta match (two per antenna) on the antenna boom as'6hown
in the drawing. This will require drilling the boom and inserting a 2"
screw.

MENT
RG-II/U PHASING LINE (2 REQUIRED)
( ) Construct the phasing lines mace of
RG-111U
coaxial cable. Two
phasing lines are required and make all measurements accurate. See Figure9.
( ) Install the phasing lines onto the antennas making certain the center
conductor attaches to the top Driven Element and the braid attaches to
the bottom Driven Element. Attach the phasing line to the Driven Element
using the tubing clamp which attaches the beta match.
NOTE:
Insulate braid with tape to prevent it shorting out on element
bracket or boom.
( ) Bring the phasing lines back to the center and down the mast. Connect
them together using a "T" connector. Feed the antenna at this point
using
RG-8/U
coaxial cable.
( ) Be certain to weatherproof all connections using Pli-O-Bond, neoprene
or some similar substance. Securely tape all coaxial cable to the boom
and mast using weatherproof tape installed every 12 in.
