Designed to work with all UHF receivers including the WiNRADiO 3000 series, the AX-37A is a compact,
directional, planar, log-periodic, UHF directional antenna. Etched on a high-quality fiberglass substrate, it includes
a surface-mount, 20 dB preamplifier, a standard 9V battery holder, power switch and an LED indicator.
Suitable for indoor monitoring, surveillance and point-to-point communication (receive only), its directivity can
substantially null co-channel interference. Its small footprint (the size of a sheet of typing paper), light weight and
thin profile invite concealed installation, quickly accomplished with double-sided adhesive tape.

WiNRADiO AX-37A Series Planar, Log-Periodic, Antennas
Create Log-Periodic Beam
The log-periodic dipole array (LPDA) is respected for its wide bandwidth, constant
impedance, and high gain. Measuring 6’8” boom length, the CLP-5130-1N (ANT16)
offers 50-1300 MHz bandwidth for transmitting and receiving, with an average forward
gain of 10-12 dBi. The CLP-5130-2N (ANT17) offers 100-1300 MHz bandwidth for
transmitting and receiving, with an average forward gain of 11-13 dBi. Ruggedly

low-loss coax.
VHF/UHF MOBILE ANTENNAS
Procomm CD144M
HIGH PERFORMANCE, LOW PROFILE, MOBILE SCANNER ANTENNA
We have replaced our popular Stealth antenna with this mechanically improved model that features
a tight hold, wind resistant, chrome finish, 3.25” magnetic base built to withstand high road speeds.
The 20” stainless steel whip can receive 25-1000 MHz (best above 100 MHz) and makes a great 2
meter transmit/receive antenna, or you can shorten it to resonance on any VHF-HI or UHF band of
your choice (Allen wrench included). 12 feet of RG58/U coax cable (not the usual, lossy RG-174/U)
is terminated with a BNC connector for your scanner or transceiver.

AOR MA500
For mobile applications, this magnetic-base, center-loaded, 24” trap-loaded whip provides superior
VHF/UHF reception from 30-2000 MHz, and can be used for transmitting as well on VHF-HI and UHF
land mobile frequencies. Includes 25 foot RG58U cable with BNC and PL-259 connectors.

WiNRADiO AX-37E Weather-proof, Planar, Log-Periodic Antenna
Designed for permanent, outdoor mounting, this rugged, encapsulated antenna has virtually the same dimen-
sional and electrical specifications as the AX-37A, but weighs 2.6 lbs and must be powered with 12 VDC @ 65
mA through the coax, requiring a “power T” (RF+DC combiner) at the receiver.
Requires SMA adaptor.
