After next January, the satellites are going to stop listening for 121.5
MHz (too many false alerts), and instead only listen for 406 MHz. So
you best bet is to buy a new ELT next year.

strongly in the success of the operation."
The poor performance of 121.5 MHz probably contributes to that. The 406
MHz signal will offer better accuracy at determining your position, and
do it faster, too. Remember the accident that spurred closing a
loophole that allowed business jets to fly without ELTs: A Learjet with
no ELT went down within 30 miles or so of taking off of Lebanon, NH, but
due to snow cover and then dense forest, they didn't find it for over a
year . . .

Hi Vern,
When my battery is low the Plane Power Alt pulls over 4 amps with the master on.
I have had it pop my 5amp field breaker. I increased my C/B to 7 amps and
haven't had any more problems. Once the engine is running, the currents drops
down to less than 1/2 amp on the field line.

Tom Velvick

Admittedly, my 121.5/243.0MHz ELT offers little insurance in case of a
crash. Not only is it old technology, but in the best scenario it will
probably go undetected for the various reasons that Bob stated. (Case in
point, who knows what direction the antenna will wind up in after a
crash?) That is why I did not go to the extent of doing the antenna in
the best fashion that we know how to do. However, even after emergency
services stop listening, it still meets the FAA requirement for an ELT
as detailed in the recent EAA Sport Aviation article. My question was
simply trying to determine if what I did was next to useless or had a
reasonable chance of radiating some RF energy.

Good Afternoon Jose,
Please understand that I am not an expert on the FARs and I have very little
electronic knowledge, but I do have a question concerning your antenna
installation.
Is it not true that the ELT is a required piece of requirement?
Because of that, is it not true that the emission from the ELT must meet
some certain standard?
The last one that I installed did have specifications concerning the
available signal emission. It said the antenna that came with the set OR an antennae
that met specified standards must be used before the ELT met the regulatory
standards.
I realize that many regulations do not apply to OBAM aircraft, but I would
not be surprised if the regulations concerning the ELT must be followed.
Any thoughts thereon?
Happy Skies,
Old Bob

Sounds like you have a realistic understanding of the
capabilities/limitations for the system. The simple answer
is, "yes, the thing will radiate . . . and probably no worse
than some less-than-ideal installations found on some certified
aircraft." Best yet, it keeps those-who-know-more-about-airplanes-
than-we-do at arms length . . . for awhile.

Oh yes, the 125.5 ELT has to have an RF power output of just 100mW...PLB's
(or 406MHz ELTS) have an output of 5W...I.e a 50 times stronger signal...Ap
parently the signal even punches through tree cover.
Its the emergency equivilent of a big battery drill compared to a screwdriv
er...:)

I'm not 100% sure, but if you are talking about an Artex ELT, I believe that
the TSO covers the unit AND the antenna. If you don't install the correct
antenna properly, you won't meet the TSO. And that could lead to an
inspection problem.
You might want to check the manufacturer's website.
Thanks!

There's a good amount of the western US over which I have flown where the
minimum radar altitude is above 11000MSL. The MEA on the route between
BOI and TWF is 10000MSL and there aren't any passes to cross; the route
can be comfortably flown at 5500 - and not be even slightly close to
terrain. Having to climb to 10000 on such a short trip isn't particularly
efficient... I agree with the philosophy you are proposing however.

Hi Bob S.,
Because of that, is it not true that the emission from the ELT must
meet some certain standard?
------A good point worth considering. I do not have an anwer nor meter
to check the output. Best I can do for now is just do a tower check on
the hour. I do know that my ELT came with a simple (non-loaded)
telescoping antenna (which had broken and dissappeared) and I think the
solid wire antenna I made is hopefully as good as that one.
Eventually, 406MHz and/or APRS is the way to go.
--Jose
PS-This is the best list ever. Thanks everyone.

Bill,
At one time, those manuals were concealed on the Garmin website, but
they seem to be unavailable now.
The revision M is downloadable from my website :
http://contrails.free.fr/download.php
Scroll down to "Avionique" then "GPS Garmin series 400"
Hope this helps,

You are correct. All ELTs must meet TSO, and TSO includes antenna spec.
Even a different brand antenna for ELT does not meet letter of the law.
And yes, it doesn't matter whether experimental or type certified, both
are required by reg to have TSOd ELT.

Gentlemen all, you are gussing.
Call PP & send it back. Get the real reason. PP does modify the
regulator & therefore he's the source of creditable facts. I can say
a stock ND should not get hot with BAT/ALT on, but I stand to
be corrected. I never tried it. However............
For a regular internally regulated ND alternator, if it uses more than
50 millivolts, with the engine shut down you have voltage regulator or
diode issue. Internally regulated alternators do not have a FIELD
WIRE of course.
