INSTALLATION PROCEDURE
After removing the antenna from the shipping box, in-
1.
spect it to be sure all parts are on hand and that there is
no physical damage.
2. Inspect the antenna feed assembly output connector to
determine that it mates with the end of your station trans-
mission line. Do not remove any connectors or cables
from the antenna feed assembly since they are all a
part of the antenna.
3. Verify that the frequency to which the antenna has been
tuned is the frequency on which your radio system is to
operate.
4. Slip the mast sections together and position the bands
as shown in Figure 5. Tighten the bands securely; the
recommended tightening torque is 45-60 in-lbs. Then,
join the connectors, making the connections snug, but
do not apply heavy force with pliers. Carefully wrap
Vapor-Wrap
®
around the connection to seal out moisture
problems. Secure the connectors to the mast with
several wraps of tape (see Figure 5).
5. Attach the furnished DB365 mounting clamps to the
bottom of the antenna mast at the designated locations.
Mount the antenna on the tower with the bottom dipole
above and facing away from the tower.
6. A check of the antenna VSWR as measured at the antenna
is recommended at this point. Note this measurement
carefully, and record it for future reference.
7. After checking the VSWR at the antenna, connect the
station transmission line to the antenna; make the con-
nection snug, but do not apply heavy force with pliers.
To avoid moisture problems, carefully wrap Vapor-Wrap
®
around the connection, smoothing it into the cracks and
over the outer jackets of the transmission line. Failure
to waterproof the cable connection can result in improper
operation of your antenna. Properly secure the feeder
cable and antenna transmission line to the tower in the
best position to avoid physical damage to the cable.
8. After the antenna and transmission line installation has
been completed, a careful check should be made to
ensure that:
• All mechanical connections have been securely made.
• The antenna is mounted on the proper leg of the tower
with sufficient physical clearance.
• All connections have been carefully wrapped with
Vapor-Wrap
®
to prevent moisture problems.
