8-1. SITE INFORMATION
. The AS-3226C/URC VHF Antenna is designed primarily for
shipboard installation. The antenna can also be used at shore installations. The antenna should be
installed in a non-obstructed environment, preferably more than 30 feet from any contiguous
structures, such as masts, bulkheads, or other metal objects.
8-2. TOOLS AND MATERIALS REQUIRED
. No special tools and materials are required
for installation.
8-3. UNPACKING AND REPACKING
. Table 1-2 gives data on the overall dimensions,

antenna from the container. Save the container to pack the antenna for reshipment. No special
handling procedures are required; observe normal precautions when handling the antenna.
8-4. FOUNDATION
. The antenna should be installed vertically on a mounting plate that has
bolt holes matching those in the antenna base (see Figure 8-1). The mounting plate must have a
center hole to accommodate the transmission line to the antenna.
8-5. INPUT REQUIREMENTS
. The antenna has an RF power handling capability of 1000
watts in the 30 to 108 MHz frequency range.
8-6. INSTALLATION PROCEDURES
. After unpacking the antenna, proceed with its
installation as follows:
a. Examine the exterior of the antenna for damage; make sure that the RF connector is
not deformed, misaligned, or fractured.
b. Perform an insulation resistance test in accordance with step 1 of Table 5-2.
c. Check the voltage standing wave ratio in accordance with paragraph 4-4.
d. Place the antenna on its mounting plate. Tilt the antenna to connect the input cable to
the RF connector.
e. Secure the antenna to its mounting plate with six 1/2 in. bolts.
