2.4 GHz LINEAR ANTENNA 30-0037
Directional antennas are used in land mobile applications for a variety of purposes. As base station antennas,
they are used to provide a focus of signal strength in one direction while decreasing reception and
transmission in other directions (see diagram). In control applications they are used to aim as much energy in
one direction as possible to provide a reliable communications path.
Our linear antennas are housed in a durable PVC tubular housing. Antennas features a rugged, U-bolt type
mount. The system is completely sealed to keep out the weather and to prevent unwanted detuning. Antennas
feature 12 ” of RG58 cable with a ‘N’ Female connector for attachment to GINA.
