L14205 900 MHz 6 dBd Yagi Antenna with Mounting Hardware


The 14205 is a high-gain (6 dBd), directional (Yagi) antenna. It is useful for making RF links over longer distances in one direction. The 14205 requires an antenna cable to connect it to the spread-spectrum transceiver. (See the Compatibility information for cable options.)

Additional Compatibility Information

Spread-Spectrum Transceivers

Note: Because the FCC limits the EIRP of 900 MHz spread-spectrum radios to 36 dBm, using this antenna with an RF450- or RF451-based system may require the user to reduce the radio's transmit power to a setting of 9 or less.

Antenna Cables

The following cables can be used:

  • COAXNTN-L—connects the antenna to the radio, data logger, or interface via a surge protector.
  • COAXRPSMA-L—connects the antenna to spread-spectrum radios other than the RF450 when surge protection is not required.
  • COAXSMA-L—connects the antenna to an RF450 when surge protection is not required.

Mounting Hardware

The antenna includes zinc-plated mounting hardware that accommodates a pipe of up to 7.62 cm (3.0 in.) outer diameter.
