the outer jackets of the transmission line. Failure to wa-
terproof the cable connection will result in improper op-
eration of the antenna.
9.
Secure the feeder cable and antenna transmission line
to the tower in the best position as to avoid physical
damage to the cable.
10. After the antenna and transmission line installation has
been completed, a careful visual check should be made
to ensure that:
•
All mechanical connections have been securely made.
•
All connections have been securely wrapped with
VAPOR-WRAP™ to prevent moisture problems.

120 MHz. Two clamps are provided with DB201 anten-
nas in the 30-120 MHz frequency range. Tighten the
mounting clamps securely and evenly. If two clamps
are used, ensure that the clamps are vertically aligned.
5.
Using the supplied lockwashers and nuts, install the U-
bolts onto the base plate, leaving them loose enough
that the ground radials can be placed between the U-
bolts and the base plate. Slide the radials in until they
touch against the side of the adjacent U-bolt. Then,
tighten the U-bolts securely and evenly.
6.
Mount the fully assembled antenna onto the tower en-
suring that the antenna is vertical and that the mount-
ing clamps are tightened evenly and securely.
7.
It is recommended that a check of the antenna VSWR
is measured at this point. Note this measurement care-
fully and record it for future reference.
8.
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 prevent moisture problems, carefully wrap VAPOR-
WRAP™ (11317 or 11316) around the connection; work
ing the compound into all cracks and smoothing it over
