Installation of the Shively Labs Model 6020 antenna is
straightforward. This instruction sheet contains all the infor-
mation you will need. If you have any problems, call Shively
and talk with your Sales representative.
Check Shipment.
Before beginning, be sure to check your shipment to be sure
all the parts are there. The parts are listed on the installa-
tion drawing.
Installation.
DANGER!
Whenever personnel are on the tower in the area of
the antenna, shut off the signal and lock it off so that it
cannot be turned on accidentally. RF emissions at close
range are hazardous.
CAUTION
Do not overtighten hardware and flange connections.
Overtightening them may damage components or affect
your signal. See Table 1 below.
Do not alter the length of the boom from the mounting
pole to the arms. Doing so will affect tuning and antenna
performance.
a. Lay the system out on the ground and verify fit of an-
tenna, mounting brackets and feed system components.
Inspect connection points for damage.
b. Mark the outrigged pole at the location where the antenna(s) will be mounted, in accordance with the installation
drawing. Watch for tower components that might interfere with your installation. Verify this location is free of tower
paint and that a good ground contact will be made between the mount and the tower.
c. Mount the antenna bay on the pole at the location you marked (step b).
CAUTION
Semiflex cable has a minimum bending radius, specified by the manufacturer. Bending it too sharply will damage
the cable. See Shively Labs technical bulletin "tb-coax installation" for installation guidelines.
d. Be sure the tower transmission cable flange contains an inner conductor connector. Install an O-ring in the flange,
Carefully insert the inner conductor connector into the inner conductor in the antenna, then attach the cable flange to
the flange at the rear of the antenna bay as shown in the installation drawing. Tighten the flange bolts to the torque
specifications shown in Table 1.
