AX-37-HGO (hand-grip option) $149.95
|
The AX-37AM (formerly AX-37E) antenna is a compact,
planar log-periodic UHF directional antenna with an in-built 20 dB
low-noise amplifier. The antenna is suitable for wireless networking and
point-to-point communications where its directional characteristics can
significantly improve rejection of interfering signals, as well as for
monitoring and surveillance applications.
The AX-37AM (formerly AX-37E)antenna is encapsulated in a ruggedized weather-proof enclosure suitable for permanent outdoor installations. The antenna covers a frequency range of 300 to 3000 MHz (a much wider frequency range can be received with reduced gain). While designed to be entirely general-purpose and performing well with any third-party equipment, the WiNRADiO AX-37AM (formerly AX-37E)planar log-periodic antenna is especially suitable for WiNRADiO 3000 Series of receivers, such as the WR-3700e receiver.
