aerial
To drill the holes for the aerial installation it is necessary to position the drilling-
template supplied with the aerial left of the centre line at the bottom of the
engine compartment.
The two 5mm mounting holes have to be drilled and deburred afterwards. The
aerial feed-through is also pre-drilled with 5mm and then enlarged to 13mm.
The support face on the outside of the fuselage has to be cleaned with acetone.
Apply silicone to the support face of the aerial and mount according to drawing,
including the mounting plate supplied with the aerial.
Drill a hole for the aerial cable through the firewall and the main bulkhead,
12mm above the fuselage glued joint, pre-drill to 5mm, then enlarge to 13mm
and insert a fireproof rubber bushing.
Warning
: Drilling through the bulkhead demands a great deal of attention in
order to prevent damaging wires in front of the bulkhead.
