ariel mounting support is constructed from two pieces of Aluminium sheet.
A hole is drilled in to the base of the Aerial & a Resin
mixture carefully poured in, the one used in this model
was "Araldite" a two part resin, a 6 mm bolt is now
carefully inserted in to the hole insuring that it is at
right angles to the base, the resin should now be left to
harden over night, the Aerial base can now be carefully screwed in
to the threaded hole on the base plate,
The depth of the drilled out hole should be 26 mm

Two angle's of the Aerial base cast from an original
Aerial base allows variable angle's to be set. Carefully drill a 7mm hole to a depth of 38 mm
insert cable & hold in place with Epoxy resin as
before.

on a recent " combat " mission a design flaw presented itself with this version of the aerial base, the bolt which was inserted in to the base was not of sufficient depth to fully strenghten the aerial base.

to further strengthen the spindle of the aerial base i now have inserted a bolt of approx 70 mm, same procedure as above for inserting bolt.

I have designed a more robust Aerial base the resin version was not robust enough to support the main Aerial if the Radio was being moved around
