I had the Artex 406 ELT fitted in my aircraft (until an adaption of the
regulation made the use of a certain PLB possible, and I replaced the
Artex by a PLB).
The Artex was working fine though. I had it placed on an aluminium mount
directly behind the bagage bay D-panel, with the antenna inside the
fuselage on top of the Artex-unit itself, connected via a short coax cable.
It took some work to get the mount to double duty as a ground plane for
the antenna. I had to install ONE(!) radial which I tuned on 121.500
MHz. The radial is a 1/2 inch strip of aluminium with drilled holes in
it. The whole setup is sturdy but light weight.
(For the technically interested reader: the tuned radial is an
acceptable trick. Instead of a ground plane of random dimension, you can
use ONE thin straight "ground plane" strip, provided you tune it to a
specific length. As seen through the eyes of the Artex, the antenna is
now no longer a 1/4 wave on a ground plane, but a center fed 1/2 wave.
Although it looks very different to the human eye, technically it is
similar to the COM antenna in the tail, which is also a center fed 1/2
wave without ground plane. I used the original Artex antenna for this
setup as one "half" of the antenna. The Artex sees a 50 ohms impedance
and is perfectly happy with it, as its diagnostic test indicates. To be
even more correct, the antenna also needs to be in tune at 406 MHz. This
is achieved by giving one leg of the mount the correct resonance length
for 406 MHz.)
I think this is the best solution. The aluminium mount works as a "shock
absorber", and by mounting the antenna on the unit itself, it gives the
best chances that in a fuselage scattering crash the unit and the
antenna don't get separated.
If you are interested, I have the mount still lying on my bench, and I'm
willing to ship it if you care for the shipping costs. I can also
photograph it, but to fit the thing in the curved fuselage I had to
shape everything to fit, and it is hard to describe exactly the angles
and curves of the aluminium, and if you reproduce it chances are that it
won't work unless you have the tuning tools and experience yourself (but
in that case you weren't asking about it anyway).
One final comment: The installation calls for a switch with an
indicator, and a connection to a power supply. The external power supply
is ONLY used for feeding the diagnostic LED. It is a shame that this
external power is mandatory, as it requires a non-switched "life" wire,
something you not exactly desire if you are lying in a puddle of fuel
after the crash.
So solve this matter, I installed a resistor of 1K in series with the
power supply. This limits the current to 12 mA, not sufficient to burn
anything or even cause a spark, but enough to lit the LED and make the
authorities happy.

Many thanks to everyone who responded to my message:
Brian - many thanks, useful info, I'll fit the Aircraft Spruce
berarings, and monitor. Still here in Kenya, weather great, bureaucracy
awful. Re aviation, all former Permit aircraft are now on a Restricted
C of A (since 3 years), and under this category such aircraft 'may not
make international flights', which locks us all into Kenya. I assume
that the aircraft becomes unairworthy once it crosses the border. This
affects 50 aircraft, 15% of the Kenya civil fleet, but it only seems a
few are interested to travel to neigbouring Tanzania or Uganda, or
further afield. I suspect that there are many kitfoxes and similar in
the remote ranches who no longer bother with CofAs and all that. I used
my Europa for commuting to Uganda, and no longer can, hence last year
did only 6 hours in it. For my wildlife projects in Uganda and Tanzania
I now have to hire a Cessna, and 4 time the cost.
Remi- thanks for the info. I'll try the AS option above, but will test
performance, and bear your recommendation in mind.
Peter and Keith in New Zealand, re Artex 406. Thanks for very much for
your help. Are your antenna(e) internally mounted? And Peter, the
groundplane plate is a flat plate, and the diameter and thickness? I
think the Artex 406 system has many problems as you indicate.... here
in Kenya, an Artex went off in a parked Cessna, 100 m from the control
tower of our busiest airport Wilson. The signal was picked up and
reported (apparently) by a passing British Airways boeing. The ELT
bleeped away for a week with various people running around the wider
countryside of Kenya before someone peered out of the tower and realized
it was just there... Tells you alot about many things...
Thanks again, all best
Richard
