Refer to
Figure 4
and install one of the two wires (both are the same length) from the brass block to
the
AVA-2
antenna
ANT +
connection, use the wing nut and hand tighten only. The wire is held
in place on the brass element block with one 5/16" x 1/2" bolt and one star washer. The closed lug
goes on the brass element and the open lug goes on the
AVA-2
.

The other wire goes from the
ANT -
(use the wing nut and hand tighten only) on the
AVA-2
to the
ground tab on the stainless steel V-Clamp installed on your ground rod as explained in the next
section. The closed lug goes on the ground tab and the open lug goes on the
AVA-2
as shown in
Figures 5
and
6
.
Ground Mounting Rod
Drive your four foot copper clad steel ground rod into the ground far enough to provide a sturdy
mount for the antenna system. Ensure the
ARAV3
unit will be above any potential standing water.
Depending on soil conductivity, increasing ground rod depth
beyond a few feet for an active receive antenna rarely improves
RF grounding because skin effect in the soil prevents current
from flowing deep in the soil. Avoid ground rods less than 5/8"
in diameter.
Position the
ARAV3
unit on the ground rod adjust the height
so the ground rod top is not higher than the
ARAV3
black
insulated panel. This prevents unwanted interference with the
active element. Tighten the two V-Clamps to hold the
ARAV3
in place.
Attach the V-Clamp with the tab to the ground rod just below
the bottom of the
ARAV3
as shown in
Figure 5
. The V-Clamp
can work with ground rods from 5/8" to 3/4" in diameter.
