AX-31CMX Planar Log-Periodic Antenna
Ruggedized enclosure for outdoor mast-mounting, no preamplifier, receive and transmit
>>> Prices and availability on request!
The AX-31C antenna is a compact VHF/UHF log-periodic directional antenna, a successor to the popular AX-31B antenna, with improved performance and reduced weight and dimensions, as well as additional packaging options: an outdoor mounting version and a hand-held one.
This antenna is constructed on a high-quality fibre-glass substrate, with an integrated low noise amplifier. The user can also specify antenna versions without the inbuilt amplifier, which does not require any power to operate. Versions without the amplifier can be also used as low power transmit antennas.
The AX-31C antenna covers a frequency range of 290 to 2200 MHz (a wider frequency range can be still received with reduced gain) and is ideally suited for reception of point-to-point communications where its directional characteristics can significantly improve rejection of interfering signals. The directionality is especially significant above 400 MHz; under 400 MHz the directionality gradually declines to the point when the antenna acts as a non-directional dipole.
While designed to be entirely general-purpose and performing well with any third-party equipment, the WiNRADiO AX-31C antenna is especially suitable for WiNRADiO G3 Series of VHF/UHF receivers, in both professional and consumer applications.
The antenna comes in several versions. The AX-31CMX version - the user can specify an antenna model without the internal amplifier, which does not require any power to operate. Such antenna can be also used for low-power transmit applications.
