the washers that are always used, three standard 10 mm
spacers used for a typical installation on a non-tilting surface
and standard length M5 stainless steel bolts with nuts – Note
length may have to be adjusted to accommodate a tilting
surface.

Drainage of the antenna

In order to keep the height of the antenna as small as possible
and in order to avoid the complex and often unreliable
complete sealing of the antenna a simple mechanism in the
form of three holes in the dome (plastic enclosure) bottom is
used. The holes are made so that water e.g. solid drops is not
likely to enter the dome and simultaneously water that
incidentally has entered the dome or moisture condensed in the
dome is drained out simply by gravity. Correct function of the
drainage system will only be ensured by following criteria 1
and 1 above.
