Hi=2C
Can any one tell me the best way and position for mounting a VOR aerial in
my
Europa?
I put mine inside the fuselage and it has not worked!
Comments please.
Thanking you.

Hi Michael,
I put a Bob Archer antenna in the roof of my aircraft and it works
fine. I originally had it in the floor but the Glideslope & Localizer
didn't work as well.
Regards, Paul

Hi Michael
It wont be relevant if you have a classic or XS wings already skinned,
I fitted Dual Bob Archer VOR aerials in the wing tips with a Garmin splitter using
RG400 cable, It works fine for all VOR/LOC/ILS.
regards
Ivor

Paul-
Just for clarification, was that (vor) antenna placed front-ward or
rear-ward with respect to the pilot.
I am considering putting the glideslope antenna on the top of the fuselage,
just behind the front window, and am wondering what the results have been of
any ground plowed before (for example: prop interference).
Thanks in advance,
Greg

Michael,
you might improve reception by taking note of the polarization of the
signal: while Aviation Radio is vertically polarized, VOR-signals are
vertically polarized.
The Europa fuselage is radio-transparent - no need to mount the antennas
externally. That further cleans up the plane.
I assume some wiring problem being the cause of your NIL-reception as
polarisation does not result in such dramatic LOS (Los of Signal).
BTW, the pilot is a small obstacle for radio waves, too. I would try to
stay away from the engine and instrument panel as there is a cloud of
noise generated.
As Paul suggests: the wingtip is an excellent choice if you can live
with one more connection to be done when mounting the wings.
good luck !
Thomas, N81EU

Its a while now but our VOR is a copper tape dipole mounted horizontally in
the bottom of the rear fuselage - about 18" behind the rear baggage
bulkhead. Not sure of the dimensions but would guess a 1/4 or 1/2
wavelength.
We dont use the VOR a lot but it has always worked OK.
When you say it has not worked what do you mean ? Almost anything will work
but if its wrong then not very well - ie: poor range. I would guess there
could be a problem with the coax - is it the correct grade - also is there a
carbon toroid (ring) or several at the dipole end ?
My Physics is a bit rusty but i am sure there are those that would know the
formula for aerial length. v = f X wavelength (I think) though im not
sure what v should equal ?
Hope that helps.
