VHF/UHF BASE ANTENNAS
The AX-31B antenna is a compact UHF directional antenna with an in-built
amplifier, which provides a low-cost alternative to conventional UHF antennas (for
example discones), especially for indoor professional and amateur applications.
This log-periodic antenna is constructed on a high-quality fiber-glass substrate,
with a 20dB amplifier directly mounted on the substrate, together with other sur-
face-mount circuitry and a standard 9V PP3 type battery holder. A power switch is
provided directly on the antenna.
In professional applications, this antenna is ideally suited for EMC pre-testing, surveillance and monitoring.
The antenna covers a frequency range of 230 to 1400 MHz (slightly wider frequency range can be received with
reduced gain).
The AX-31B antenna package includes a 2 meter (6.5 ft) cable with an SMA connector for the antenna and a
BNC connector for the receiver. Battery is not included.
The antenna is designed for indoor reception. Its small footprint, the size of an A4 sheet of paper (11.5” by 8.5”),
conserves space and makes concealed installation possible, if desired. The antenna is lightweight and installation
can be achieved within minutes using double-sided adhesive tape.
WiNRADiO AX-31B Active UHF Antenna
Imagine improving your VHF/UHF base station communications or scanner
monitoring by substituting one low-profile (17” H), multi-element antenna system
on your antenna line! Its patented, tilted, three-element design uses harmonic
patterning to improve VHF/UHF reception and transmission without retuning (see
pattern link below)! Ideal for modern, 25-1300 MHz, wide-coverage scanners,
and for 100 watt commercial, amateur, and government transceivers operating
in the 140-174, 216-225, and 406-512 MHz ranges.
Its broadband design accepts modern repeater splits, cross-band, and
wideband spread spectrum. Unique sloped elements reduce picket fencing.
Stainless-steel whips with turn screws fit securely into an NMO aircraft aluminum
base fixture. The antenna assembly clamps securely to your tower or mast pipe and is equipped with an SO-239
connector to match your PL-259-equipped coax cable.
