Nigel-
What Alan says about the AAE antenna is dead on.=C2- It is a folded diplo
e, as opposed to a dipole, therefore the bandwidth is about twice that for
a given SWR as a dipole.=C2- In addition to the AAE in the rudder, I have
a second antenna installed just aft of my baggage bay.=C2- I used 1/16 p
lywood, 3/4 inch wide, covered with 2 plys of BID=C2-and extended it from
the floor to the celinig just aft of the "D" bracket, with another piece a
bout 8 inches long going from the middle of that piece to the aircraft skin
about on the line between the upper and lower canoes.=C2- Copper strippi
ng is fastened to it and center fed with RG58U.=C2- The ends are bent, th
e top across the top of the roof, the lower along the floor for about 6 inc
hes.=C2- This doesn't matter much, the most critical part of a dipole is
the center portion, the further out you get, the less sensitive it is to be
nds and distortions in the tape.=C2- You can easily tune it using an=C2
-SWR bridge.=C2- The AAE antenna does not need to be tuned; if=C2-fac
t, if you attempt to tune it, you will destroy it.=C2- My second antenna
was installed=C2-for=C2-amateur use at around 144 MHZ.=C2- The tape i
s a very inexpensive and very effective answer for the comm antennas, but t
he AAE is a good choice for permanent installation in the tail .=C2- =C2

Good comment Nigel,
I have installed all three but prefer the carbon fiber Advanced Aircraft El
ectronics (AAE) antenna=C2-types because they are "no brainers".
Hook an AAE to your handheld and it is a great backup=C2-for anyone.=C2
- Heck, just tack with super glue in spots between the epoxy aft of the a
rea behind the bulkhead for a quick retrofit.=C2- Use it for your ELT als
o if you want instead of rigging a ground plane.
I can hook my "Sporties SP200 to the AAE antenna and it is as good as the N
arco.
If you need to make an antenna, by all means get an VSWR meter and tune it
to make it perfect.=C2- It is only=C2-a few dollars but time and tuning
is spent also.=C2- Personally, the older I get, time is a precious commo
dity.

I think the various comments made on this subject shows that the
installation is probably more important than the choice of product.
There have been many positive and negative comments about each type of
antenna. Quality of the connections and avoiding tight bends in the
cable are important considerations.
I am considering putting a second antenna into the fuselage to enable my
handheld to be used as a backup radio. Handheld radios will work well in
the aircraft provided they have a proper antenna. The short rubber
antennas give poor transmission and are useless for a touring flight
such as a crossing of the English Channel.

Hi Bill
I have the normal Europa copper tape Di-pole on the stern post and a Bob
Archer Just behind the D panel Port side, To be Honest the Copper tape
antenna works much better, Have read ATIS at over 70NM with a Xcom and
about 50NM with the Garmin SL30 using the Bob Archers,
regards
Ivor

more technical than I can follow.=C2- The volume of this data possibly
suggests the amount of not easily solved problems with antennas.=C2- I
thought I had come to an installation solution that would bypass most if
not all the potential problems until I read that some are having trim
servo interference problems with the comm antenna.=C2- I had intended to
install the Archer "v" configuration antenna in the fin and a second "s"
configuration comm antenna on the fuse side rear of the baggage
compartment.=C2- The Archer information says inside the fin is the ideal
place for a glass plane considering it needs to be placed in a vertical
plane.=C2- My transponder antenna is to be on the rear fuse bottom side,
reasonably far away from the cockpit.

> Has anyone installed an Archer comm antenna in the fin without having
to shield the trim servo and its wiring?=C2- I intend to follow Archer's
instructions using proper shielded cable and also staying as far as
possible from other vertical metal objects and mindful of establishing
adequate grounding for each component.
