plastic plumbing pipes. Make the end-fed antenna as long as possible in an “L” shaped
configuration, as illustrated in Figure 4.7.1.

4.8 Aircraft Antennas
When installed in high performance turboprop or jet aircraft, the Smartuner will
operate well with a shunt-fed antenna.
This is generally a 13-foot piece of metal that mounts on the fuselage of the aircraft and
is grounded to the aircraft at one end. The device looks something like a towel bar on
the underside of the aircraft.
The Smartuner will also match well the more common wire antenna from fuselage to
vertical stabilizer (and continuing to a wing tip, if desired) and a long wire antenna
under the tail rotor of helicopters. This long wire approach has proven effective on Bell
Jet Rangers and Long Rangers in particular.
