Try it Tom. To get decent feedback while rigorous range-testing you must
first locate an open area with as few metalic obstructions as possible.
The reason is quite a bit of reflective energy is seen by the RX which
significantly skews your results. Even your vehicle parked nearby has
enough

Indeed it will. I'm not making this up. Read what Peter Berg, designer of

Excellent post! Lots of good information, Doug.
Here's a minor nit-pick:
(Now, if you add another 1/4 wavelength, or a multiple of
that, you'll probably slightly improve range. But only slightly.)
I'll bet you were really talking about adding another 1/2 wavelength or
multiple of that. Adding

Well now,
In fiddling with a 72MHz RX in a particular plane (Pike), there were
only two solutions that gave an adequate ground range-check:
1. Stock length antenna dangling straight out of the cabin, 90 degrees
to the fuse. Quite impractical. Any other solution involving the
standard

A range check where you collapse the TX antenna is hardly a scientific
test, but it does catch gross

I've used the Smiley antenna on an Airtronics Stylus transmitting on 50
MHz
(six meters). I mainly fly sailplanes and I never had a problem with
range

Range check( Full Ant ) before you install the Antenna by having some one
drive with your radio and find out where it starts to fail.( a 2 way radio
works good here) Mark that location and do the same with your new Antenna...
