Hi
My -10 has three Comant anntennas (two bent whip comm) and one cvat's whiskers
VOR/ILS under the tail.
For my new project I have been wondering about alternatives. For example, does
anyone have real world experience wit the Bob Archer wing tip NAV and COMM antennas.
I have an Archer NAV antenna that I didn't install.
Has anyone tried bonding a comm antenna into the -10 fiberglass canopy. Is this
even possible?
It would be nice to hide the antennas if it can be done effectively. I am quite
interested in what others have done.
Inquiring minds need to know

I have the Archer Nav antennas...one in each wing. I have a Garmin 430 and
a Garmin SL30. Reception is good, not great. I have a splitter for the GS
signal.
I have Comant antennas for comm.

Keep in mind that VORs transmit horizontally polarized signals, while coms are
vertically polarized. So you want the antennas the same way. There are lots of
small horizontal GS antennas embedded in the fiberglass roof, or even at the
top of the windscreen on some Cessnas. They work fine. For com, you'll need to
get it as vertical as possible. Most of the vertical antennas are 1/4 wave, and
need a good ground plane to work. This will be tricky on the cabin roof.
I have two Archers-the VOR antenna in one wingtip, the com in the other. Make sure
you follow installation directions and have a good connection between the
'ground leg' and the wing rib. For the com, I mounted the ground leg as high as
I could, then bent the leading edge down as far as possible, to get at least
some vertical polarization. I'd say the nav antenna works fine-rock solid on
ILS signals, and almost as good as an external dipole on distant VORs. The wingtip
com is just fair - not vertical enough. While my belly whip gets the ATIS
30 miles out, I need to be within 20 miles for the wingtip. I use it for my backup
com, and for that I think it's okay.

I have Archer antenna in each wing tip for GTN650 and SL30. Seems to work
fine.
A friend put Archer com antenna in one wing and nav in the other. The com
has to be mounted with vertical orientation.
It worked okay until he used a metallic paint on wing tip. That cut his
usable range down under 10 miles.

The Archer wingtip NAV antennas work pretty darned well. The Comm's will
"work" (and I use that term loosely), but not anywhere near the same as an
external whip or bent whip. Same with the bonded in versions in the canopy,
gear leg, et.al that have been tried in every configuration for many years.
Save yourself the hassle (believe me when I say "been there done that" on
both my own planes as well as customer planes) and just put the COMM
antennas externally on the fuselage. It'd be sad to have good radios
(whichever ones you use) be hamstrung by sub-par antennas.
Just my 2 cents as usual (but this one I have some rather extensive
firsthand knowledge of).
Cheers,
Stein

My experience matches Stein's advice.
I originally had an Archer Comm and Nav with the Comm mounted as
vertical as possible in the tip per everyone's advice. They were both
attached to the G430. It 'worked' but found it often lacking the
necessary range at times. I also had an SL30 with a bent Comant which
quickly became the primary Comm radio. The G430 Comm was relegated to
ATIS and Ground.
But the whole purpose of 2 radios is to have backup, right? At the
furthest possible distance from home on my longest CC flight to date, my
SL30 Comm failed. Turned out that the G430 with the Archer Comm just
wasn't enough to comfortably fly across the US on IFR plans in VMC
conditions.
So, while I was comfortable flying with one Comm (and a handheld), I had
to stop and switch antennas before we could continue. The difference
was immediately noticeable; the bent Comant was far superior to the
Archer Comm on the same radio.
When I got home I installed a second Comant on the belly. Though there
are many variables in radio/antenna installations I slowly began to
realize that the G430 performed slightly better than the SL30, using
virtually identical antennas. The SL30 remains my primary but if I
ever have a reception/transmission issues, I go to the G430. (the last
step would be to swap antennas and see if that situation remains the same).
I would add that I split the Archer Nav antenna between the 2 boxes and
it performs satisfactorily, particularly during RNAV approaches.

Bill,
You could take that Archer com antenna, and lay it flat in the wing tip
and use it as a second nav antenna. That would eliminate need for a
splitter and give each nav radio close to double the signal strength.

Les: We installed a pair of Bob Archer VOR/Loc antennas 5+ years ago.
They have worked faultlessly.
