BTV Antennas
The
Hustler

4-BTV is a four-band trap vertical antenna
providing an omni directional pattern. The 4-BTV is
designed as a self supporting vertical to provide optimum
performance on the 10, 15, 20 and 40 meter bands. This
antenna is designed for installations with restricted space.
The Hustler
®
4-BTV is approximately 19 feet tall. It can also
be adapted to operate on the 75/80 meter band by adding the
RM-80S resonator and the 4457-1 three blade spider
assembly on top of the 4-BTV. If the 75/80 meter resonator is
attached to the 4-BTV, it may be desirable to guy the antenna
above the 20 meter trap with small diameter polypropylene
rope.

5-BTV is a five-band trap vertical antenna.
This antenna includes the RM-80S resonator and the 4457-1
three blade spider assembly. The 5-BTV is designed to
provide excellent performance on the 10, 15, 20, 40 and
75/80 meter bands. The Hustler
®
5-BTV is approximately 24
feet tall.
The
Hustler

6-BTV is a six-band trap vertical antenna. The
6-BTV is designed to provide excellent performance on the
10, 15, 20, 30, 40 and 75/80 meter bands, using four traps
and the RM-80S resonator. The design of the 6-BTV is sleek,
with no capacity spiders and is approximately 25 feet tall.

BTV antennas provide automatic electrical
selection of the bands through the use of optimum Q traps,
which are individually and precisely tuned at New-Tronics.
The traps are parallel tuned circuits which provide efficient
isolation between the vertical sections, permitting multi-band
operation. Efficient operation over the many ham bands at
good SWRs is possible in a proper installation.

BTV antennas were designed to provide optimum performance from both an electrical
and mechanical standpoint. Mechanically, this antenna boasts a heavy duty base and heavy duty
aluminum tubing. The mechanical assembly is accomplished with all stainless steel hardware. The
use of clamps permits re-adjustment if necessary, and allows tuning of each band. The mechanical
construction is such that guying is not ordinarily needed.
The performance provided by the Hustler
®
BTV antenna is better than any other antenna of this
type. Broad banding is such that one setting permits both phone and CW operation on most bands.
The antenna provides a nominal 52 Ω base impedance when installed and tuned according to
instructions. The radiation efficiency is equivalent to, or greater than, other trap verticals.
