Hi guys
Thanks to those that replied to my query regarding the Microair radio--much
appreciated.
my next question is about the antennae. I will be using a dipole as
described in my last post but was wondering what effect mounting the leg
that the screen of the co-ax is soldered to horizontally will
A dipole antenna is most efficient when the ends are at 180 degrees from one
another. Hams use an antenna called an inverted V to get the antenna to fit in
their backyards.
Folding the antenna this way will affect its perfoamance some but not a lot.
The closer you bring the ends together the m
Jim Weir of RST engineering has written a booklet that he sells for $5 USD. In
it he discussed everything you need to make antenna for aircraft. The articles
are not published on the web. His web site, where you can order the booklet is

There is quite abit of stuff on the web. Search Ham sites, they are loaded with
pertinent information. Aviation antennas aren't any differnt than any other com

Dean,
Transponder is 2 1/2" x 2 1/2" x 6" plus at le
And for $29, you can get the booklet and all the material for more antennae
than you'll ever need in an airplane.

Correct Orma the balun doesn't care about orientation. The mildly folded dipole
that we are discussing here will work fine. The folding affects the radiation
pattern, impedance and therefore the effeciency of the antenna, but a 90 degree
fold is not a real big deal.

The V shape of the nav dipole antenna is one

When selecting sites inside the airframe for buried antennas, keep the
polarization correct: comm radios are Vertical, and nav radios use
Horizontal.
