formed. At least one of the holes must be kept clear when mounting the antenna to a bracket. If the 
antenna is not absolutely horizontal, this must be the hole furthest down (this is where condensation 
collects).

Holes in the bottom plate provide 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 the sides 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. For final alignment of the housings, (loosely) turn to the left.

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.

Screw on the antenna cable. The cable to the receiver must have a standard TNC connector (not 
reversed as with the antenna elements) at the antenna end. At the other end, a connector
