Transponder Antenna Question

[Jay Honeck]

Will my new Garmin GTX-327 transponder work okay with my existing Narco
transponder antenna?

We're having it installed next week, or whenever the 337 is approved --
whichever comes first.

Thanks!

Transponder antennae are 'suppose' to be generic and should work with any
transponder.

You should replace the antenna and coax. Although the old will probably
work, these components are prone to fail with age and live in a hostile
environment.

Okay, I can understand replacing the coax. But the antenna?

How hostile does an environment have to be before it hurts a solid piece of
metal?

It is not so much the solid piece of metal as it is the CONNECTION to
the solid piece of metal. Water and corrosion always seem to make their way
into the base of the antenna and ruin the connection to the coax. I run a
radio shop and we throw away hundreds of stainless steel antennas every
year, because we have discovered that it is the best thing to do with them.
We replace the entire unit after about two years of use, hopefully before it
fails. Some archieolgist will probably dig them up at the dump thousands of
years from now and those bits of metal will still be bright and useful
looking.

****How hostile does an environment have to be before it hurts a solid piece

Antennas corrode from the inside out, or from the outside in, and just like
everything on an airframe, have a finite lifespan. How old is the antenna?
Was the old antenna even placed in the right place on the airframe? A lot of
times they were not, even from the factory.

Besides, transponder antennas are cheap, in the realm of aviation.

Start replacing anything and you invite "repair damage". Leave it alone if
it works.

My thoughts exactly. The only stuff that ever seems to break on my plane is
broken during repairs.
