Michael,
I can help you if Jim's advice brings you not the correct outcome.
Distrelec sells power bricks which gives you a stabilized output voltage
of 12V (up to 3A) I use them on my moving map display, input varies,
mine allows 32-9V stabilized 12 V output. That will always work

Ciao Michael,
such bei Distrelec nach Traco Power
dann kommt es darauf an, wieviel Watt Du brauchts
z.B. 3x350mA =1.05 A bei 12V = 13W Einganspannung 9-18V (sollte reichen)

| Subject: | Transponder Antenna Location |
We have been told on more than one occasion that ATC was not seeing our transponder.
We have a Garmin GTX327 installed. We are wondering if our antenna location
might be the problem, our antenna is located in the center of the airplane
just behind the firewall. At the time we installed the antenna it looked like
a good spot, but that was before we had the exhaust installed. Not sure if
the location is the problem or not, just wondering of anyone else has experienced
any problems with the antenna in this location. Thoughts appreciated.

I doubt that's the problem.. Mine's on the right side.. maybe 10 inches to the
right of the centerline (so it's not in the exhaust path)... and it works perfect..
never skipped a beat..
Have you had your txp checked per 91.413? Did it pass that inspection?

I occasionally get the same complaint. I would say on about 5-10% of the
controller changes. It seems to occur more often when headed directly at
the antenna sight and long or short range only rather than medium. It
almost always returns for the controller as the position relative to the
sight changes. The antenna is on the belly centerline about 14 inches aft
of the firewall.

It is possible the exhaust stacks are shielding the antenna in that
case. Shouldn't be to hard to patch that hole and move antenna a foot
or so to right or left of exhaust.

I'd be checking the antenna cable before I worried about the antenna
location. It isn't unusual to find a loose antenna cable in those
situations. If nothing obvious, ask avionics shop to do a field check
of the transponder, where they observe the output with a small
handheld receiver that will indicate output power. You should have had
a check like that very early in your flight test phase.

Just speculating, but I wonder with your antenna that far forward if you are
getting some issues from the exhaust pipes? As I mentioned previously mine
is a bit further back and while it does get a little dirty, it works great.

I've never seen a problem with the antenna right where you have it. I'd also check
the coax running to the antenna. How high do you normally fly?
The only problem I've noticed is in a specific area about 50 miles east of our
home airport here, so it could have something to do with the radar coverage.
I assume you've already verified that it isn't always in the same geographic area.

Kelly, we did have the typical inspection performed where he sets up a tests apparatus,
but that is done in the shop. Is there another way they test?
We have not narrowed it to a specific geographic location, it seems to happen at
random. Our suspicion is that the antenna is being shadowed by the exhaust
pipes. We were going to move the antenna back a foot or so, but wanted to get
some feedback before making an assumption that that is the real problem. If
others have it in the same location and are not having the problem then we would
need to dig deeper. We did verify the cables and connections were good.

Yes, there is a hand held ramp checker. They are supposed to test the
full system, which means receiving the signal from the antenna, not
connected to a load on the bench.
