WiNRADiO’s
AX-31B
Planar Log-Periodic Antenna
by Harold Ort, N2RLL, Editor
Once in a while an unusual, out-of-the ordinary
product comes our way that really deserves attention. Such is the case with
WiNRADiO’s AX-31B antenna. It’s a compact indoor VHF/UHF directional antenna
with a built-in amplifier — great for scanner users — or with any VHF/UHF
receiver. The frequency range is 230 to 1400 MHz.
When the company said they were sending an antenna for review, naturally I
expected a pretty large box — after all, it was an antenna they were
sending! The thin book-sized package arrived from WiNRADiO, and much to my
surprise it was the antenna! It’s just a little larger than the magazine
you’re holding right now, and weighs practically nothing — only 9 oz.
(without a small 9-volt battery attached). Constructed of high impact
plastic, this opaque black rectangular marvel can be mounted anywhere
indoors. I used the mounting adhesive, sticking it to a west-facing window.
The antenna’s large white arrow points north/northwest — the direction I
want to “point” the antenna for best reception of signals from Newark,
Woodbridge, and Metuchen, New Jersey.
Connecting the supplied six-foot cable to the antenna. The other end terminates in a BNC connector — perfect for your scanner.
