With stainless steel hardware.
The A3 World Ranger, our top selling tribander, has become the A3S with all stainless steel
hardware. It's a real power-house in a small space and lets you work the pile-ups with
confidence. All you need is a lightweight tower and rotator to enjoy the benefits of the A3S.
It's a proven performer in DX-peditions and contests and handles full power from your linear.
Construction features include pinned boom sections, heavy duty element clamps with backing
plates plus all stainless steel hardware. When space is at a premium, but you want the benefits
of a full-size tribander, the A3S is right for you! Add 40 meters with A743 kit.
Our World Ranger Dipoles give
bi-directional patterns and
rotatable convenience. You can
mount them high and away from
the trees for better performance
than a wire dipole. These single
and multi-band dipoles feature
high-performance traps, heavy
wall tubing, and rugged
hardware for years of enjoyment.

40 meters will come alive by
adding one of these kits to the
dipole of your A3S or A4S. The
kits include high power traps with
heavy wall fiberglass insulator
and all hardware.
A simple
adjustment allows 30 meter
operation. For our newest beam,
the A3WS, we have a 30 meter
add on kit the A103.

Enjoy the excitement of the WARC bands with
this popular beam.
The A3WS gives full
performance on 12 and 17 meters. With the
addition of our easy-to-use A103 add on kit, it
will also cover 30 meters. A3WS needs only a
lightweight tower and rotator or you can mount
it above an existing tribander. Construction
features include pinned boom sections, heavy
duty element clamps with backing plates plus
all stainless steel hardware.

With stainless steel hardware.
The A4S is the true, high performance tribander. Precisely tuned high-power traps, carefully
selected element lengths, and proper spacing combine to make the A4S the preferred antenna
for your HF work! This is the premium antenna with all the features that you want. High gain,
low SWR, and wide bandwidth keep the contacts coming in. All U-bolts, clamps and hardware
are stainless steel. The A4S has pinned boom sections and formed aluminum brackets to
keep elements straight under all conditions. Our solid construction keeps the A4S on the
tower! Add 40 meters with A744 kit.
