The Hustler
®
Antenna Company introduced this product over 50 years ago, with little attention to
maximizing performance. It was designed to be an easy-to-install antenna with minimal grounding,
which provided easy - or no - tuning and wide bandwidth but mediocre performance.
DX Engineering decided to take this popular product and show how its performance could be
greatly increased by proper installation, including the addition of an adequate radial ground
system. This results in lowering the resonant frequency, and also altering the impedance at
resonance. Hence - the need to adjust the traps, which was not “allowed” by the manufacturer, and
the possible addition of a shunt coil at the feedpoint.
You can install the antenna according to the New-Tronics instructions and make some contacts with
little attention to ultimate performance. Our BTV Guide takes you into areas which result in
departing from the simple installation and the need to make more adjustments than originally
described. That is the reason we designed the tilt base, for easy raising and lowering between
adjustments.
The overall experience should be an effort which started with an inexpensive trap vertical, and
finished with a high performance antenna installation providing very satisfying results.
