I have 3 Bob Archer antennae in G-OWWW. The COM and NAV
are the thin strips and I have the "two sided printed
circuit board" Transponder antenna.
G-OWWW is (mainly) a Classic and the wings were closed
when purchased.
The COM antenna is placed vertically just behind the fuel
filler on the starboard side. The NAV antenna is placed
across the top of the fuselage. It is perfectly OK for the
ends of the ali strips to be bent out of the horizontal plane.
Remember the COM antenna must be vertical and the NAV
horizontal as these are the orientation of the radio waves !
The NAV antenna will provide VOR and Localiser
information. The Glideslope in a ILS is different
altogether and needs extra kit.
