Appendix A – Antenna Specifications
The following antenna specifications are supported antennas from a standard configuration.
Only supported antennas may be used and with the power setting shown to meet FCC
requirements. The FCC approved maximum power is set in software to ensure that the
radios do not transmit above the FCC approved power level.
802.11b SLH 12dBi external
directional antennas
Description
Transmit power to antenna. Radio and system dependent, typically between 30–400
mW (15–26 dBm).
FCC approved maximum
power.
22 dBm.
Antenna gain. 12 dBi.
Horizontal beamwidth. 48 degrees.
Vertical beamwidth. 48 degrees.
Polarity. Circularly polarised (right hand orientation).
Model. SLH12.
Impedance. 50 ohms.
Coaxial cable. LMR 195, LMR 400, LMR 600.
EIRP at external antenna. Depends on radio and system losses, typically 100 mW – 4
W (20–36 dBm).
Connector. Standard TNC.
FCC Approval
The maximum power output for each RX INN is set through the RAMP
configuration software. The country setting will be set to FCC which will limit the
power output to that listed in the table above and customers will not be able to
change this setting.
