Model CB-3
CH, 3-element beam PN 805661
The Hy-Gain Model CB-3 is a 3-element. beam des igned to operate over the
entire frequency range (26,9 to 27.3 mc). lt develops a forward gain of 8 dB,
has a front-to-back ratio of 20 dB and front-to-side ratio of 40 dB.
Unpack the antenna from the carton and check the parts against the parts
Ii st. Use the drawings to help you in identifying the parts.
Select the boom-to-mast body and the boom-to-mast clamp and loosely
assemble using four 1/4"-20 x 3/4" screws in the outside holes only.
The inside holes will be used later for the U-bolts. Insert the boom tubes
(ends not drilled) into boom-to-mast clamp. Holes in tubes must be hori-
zontal. Now, tighten the four screws in the boom-to-mast bracket securely.
See Figure 2.
Select the two sets of small element-to-boom brackets and mount them on
each end of the boom in the pre-drilled holes using 10-24 x 1-3/4" screws,
nuts, and lockwashers as shown in Figure 3.

Reflector Assembly ) Select the two Rl sections (7/16 x57-112 ) and slip the end with a
hole drilled through both walls into the element-to-boom bracket that you
just installed on the end of the boom (long end). Fasten securely using
two 10-24 x 1" screws, nuts, and lockwashers. See Figure 3.
( ) Select the two R2 sections (3/8 x57-1/4 ) and slip the drilled end
into the Rl section. Line up the holes and secure using #8 x 3/8 self-
tapping screws.
Direction Element
Assembly ( ) Now select the two
01 sections (7/16 x 48") and slip the end with
the hole drilled through both walls into the element-to-boom bracket that
you just installed onthe end of the boom (short end). Fasten securely
using two 10-24 x 1" screws, nuts, and lockwashers.

Driven Element
Assembly
( ) Now select the 02 sections (3/8" x 53-1/4") and slip the drilled end
into the 01 section. Line up the holes and fasten securely using #8 x 3/8"
self-tapping screws.
( ) Select the two Driven Element brackets and install a 1/4"-20 x 3/8"
anchor screw and square nut in each of the center holes as shown in
Figure 4. Do not tighten at this time.
( ) Assemble the Driven Element bracket on the reflector end of the boom
41-5/8" from the center of the reflector bracket to the center of the
Driven Element bracket as shown in Figure 5. Do not tighten the anchor
screws at this time.
( ) Select the two DE1 sections 7/16" x 58" and slip an insulator over
the undrilled end of each, then slip the insulated end into the Driven Ele-
ment bracket. Tighten the screws to hold the element securely. Tighten
the anchor screws securely.
( ) Select the DE2 sections 3/8" x 50" and note that one has a hole
drilled 1" from the end and the other has a hole drilled 2-1/2" from the
end. The tube with a hole drilled 1" from the end is for the 2..e Driven
Element and the tube with a hole drilled 2-1/2" from the end is for the
bottom Driven element.
( ) Insert the ..Q..QDE2 section (hole drilled 1" from end) into the QQ DE1
section, align the holes and secure with a #8 x 3/8" self-tapping screw.
( ) Insert the bottom DE2 section (hole drilled 2-1/2" from end) into the
bottom DE1 section, align the holes and secure with a #8 x 3/8 self-
tapping screw.

( ) Trim back the coaxial cable approximately 7 and solder one #10
solder lug on the center conductor and one on the l"Iraid as shown in
Figure 6.
( ) Refer to Figure 6; place 7/16 clamp around the top and bottom
Driven Element tubes near the Driven Element insulator.

( ) 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.

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.

( ) 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.

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.
