Antenna Systems

The horizontal (ultra) antenna assembly can now be slid into place at the other end of each boom, and secured using the
final two clevis pins, and retaining clips. This secures the antenna assembly, and allows it to move through its full mo-
tion.
Note: There are two possible orientations for the horizontal antenna, based on your choice at time of purchase.
The correct hole for the upper pin is marked LH or RH on the antenna mounting bracket. The correct lower hole is
diagonally opposite, as shown below.

Now install the vertical plane antenna onto the top tube. Slide the antenna underneath the horizontal antenna onto
the top boom, aligning it with the existing holes, as shown. Secure the antenna to the top boom using the two 8G self
tapping screws provided. These should be hand tight.
Note: If using a cordless drill or driver, be careful to set a low
torque setting initially, so as not to strip the formed thread in the aluminium upper boom.
