There are 4 small holes in the base plate near the corners. They serve to equalize the pressure in the
housing when there are major changes in temperature, and to drain any condensed water that may have
formed. At least one of the holes must be kept clear when mounting the antenna on a bracket. If the
antenna is not absolutely horizontal, this must be the bottom hole (condensation water collects there).
Drilled holes in the base plate ensure ventilation and drainage
The assembly of the dismantled antenna is quite simple and should be carried out in the following order
(disassembly in reverse):
•
Screw the connecting rod into the amplifier housing. There is an M5 spacer bolt on the top of the
housing, into which the threaded pin at the end of the rod fits. An M5 nut should already be
screwed onto the threaded pin, which must be screwed onto the rod as far as it will go (otherwise
screw on the nut so far). Screw the rod into the spacer of the amplifier housing until it stops
against the nut. Caution! Tighten only slightly loosely to a maximum hand-tight and hold it straight,
do not exert any torque or shear force on the spacer bolts!
•
Similarly, screw the node housing onto the other end of the rod. Again, pay attention to the
presence and full screwing of the nut and the maximum light tightening.
•
Align both housings (turn them against each other) so that they are parallel to each other. The
connectors on each side of both housings must point in the same direction (slight twisting by 1 - 2
degrees does no harm). Caution! The connecting rod must not be screwed firmly into the spacer
bolts on either side! Only turn to the right (clockwise when viewed from above) until the screw
connections are at most hand-tight. Then turn to the left (loose) to align the housings correctly.
•
Counter the nuts on the threaded rod against the spacer bolts on both housings. To do this, hold
the spacer bolts with a size 8 open-end wrench and use another wrench to turn the nut firmly
against the bolt. Never grip the housing during assembly! The spacer bolts are sealed on the
housing. If they are turned against the housing, the seal will be destroyed and moisture could
penetrate! Make sure that the housings remain parallel to each other.
•
Screw on the antenna elements. The cables are already approximately semicircular, so that they
fit onto the sockets on either side of both housings without tilting. Bend a little if necessary.
Despite their relatively large diameter, the cables are easily bendable.
•
Caution! Never bend them sharply, especially not at the connectors! It is best to screw one side
firmly onto a housing and then shape the cable so that the plug on the other side can be screwed
straight and easily onto the socket on the housing.
