( ) Using a #10 x
3/4"
bolt, nut, and lockwasher, connect the coax to
these two brackets as shown. Make sure the braid is attached to the
bottom end of the Driven Element and the coax center conductor attached
to the top end of the Driven Element.
( ) Wrap the braid with weatherproof tape to prevent it from shorting out.
Weatherproof the connection using Pli-D-Bond, neoprene or some similar
substance.
Now, mount the antenna on a mast and tighten securely using the U-bolts
supplied. This antenna can be rotated with any common TV rotator. If the
antenna is mounted on a tower, make certain the mast extends above the
tower sufficient distance to allow the lower tip of the Driven Element to
be above the tower.

Assembly
Figure 7 showsthe correct assembly and all parts needed to assemble
the vertical spacer.
This connection should be made
17-112"
from the end of the bottom Driven
Element as shown in Figure 5.
Stacking Two ( ) Construct an 18 ft. boom as shown in Figure 10
Model CB·3 Antennas
( ) Form a beta match out of
118"
wire as shown. Four will be necessary
(two on each antenna). The beta match will help properly tune the antenna
to the phasing lines. See Figure 8.
