Telex RadioCom RA-3 User manual

RA-3, RA-5, & RA-7
Wireless LAN Antennas
The RA-3, RA-5 and RA-7 antennas are ideally suited for IEEE 802.11b and 802.11g wireless LAN’s and Bluetooth®applications
and other systems operating in the 2.4 GHz ISM band. The RA-3 and RA-7 are omnidirectional “rubber-duck” WiFi antennas
providing broad coverage. These exible antennas feature a tilt-and-swivel reverse polarity TNC connector allowing them to be
used vertically, at a right angle, or any angle in-between. The RA-5 is a mobile or desktop Omni wireless LAN antenna with a
magnetic base.
