Beta Match
() Select the Beta Match tubes (3/4" x 17"), the beta support insulator and clamp as
shown in Figures 3 and 6. Make certain the drilled ends of the beta tubes are pointed
towards the Driven Element.
( ) Select the Beta Match shorting strap and the shorting clamp and assemble as
shown in Figure 6. Notice that the 10-24 x 1
1/2"
screw attaching the shorting straps to
the clamp has a sleeve slipped over it. This allows you to install the shorting straps
without causing undue strain on the Beta Match tube.
( ) Install the pigtail assembly (wire with solder lug on each end) on the Beta Match
tubes using the two #10 metal screws and lockwashers. Slip the 1 ¼”
tubing clamps
on the driven element near the insulators. Loosely attach the pigtails to the tubing
clamps using the ¼”-20 x 1 ½” screws as shown in Figure 6. Do not tighten the
connection at this time. The coaxial feedline will connect to this point in a later step.
Director Element
( ) Select the remaining set of element-to-boom brackets and loosely assemble on the
Assembly
boom 80
3/8" from the center of the driven element-to-boom bracket to the center of the
Director Element-to-boom bracket. Refer to Figure 3 and 4. Do not forget the anchor screws
as shown in Figure 4.
( ) Select the D-1 section of tubing (1'/." x 28"). Insert the D-1 section into the bracket
assembled on the boom. Tighten the screws to hold the element securely but do
not
tighten the anchor screws at this time.
