# 2 Phillips Head Screw Driver
Installation
Location
The best place to install your active antenna is where you have the recommended space. The
DXE-
ARAV3
should be located a minimum of 1/2-wavelength (at the lowest frequency used) away from
any transmit antenna. If the unit is located 1/10-wavelength to 1/2-wavelength from a transmitting
antenna, the unit must be powered off at least
5 ms
before transmitting on the transmit antenna. A
sequencer such as the
DXE-TVSU-1A
should be used to ensure the correct transmit-to-receive
switching.
With this close spacing, coupling from nearby transmit antennas or metal structures becomes more
pronounced. At higher frequencies, where the active element length becomes a partial wavelength,
coupling increases further. Placing a
DXE-ARAV3
on the same mast or tower as a Yagi or other
transmitting antenna is not recommended for this reason.
Assembly
The assembly described is for the
DXE-ARAV3-1P
steel hardware threads to prevent galling and to ensure proper torque.
Orient the black mounting plate with the two brass element mounting block holes closer to the top
left, as shown in
Figure 1
. Use the 7/16" x 1-1/2" bolts, flat washers, split washers, and nuts to
mount the brass element block to the mounting plate. Make sure the threaded hole in the element
block for the antenna element is facing upward. Use a flat washer under each bolt head and a flat
and split washer combination under each nut. Do not over-tighten.
