NTENNA

Tracer is intended to be coupled with an antenna that is directional
and provides signal gain. There are several reasons for this
requirement:

• Tracer operates in point-to-point applications; therefore, an

omnidirectional antenna is not needed.

• The FCC provides no recourse in this band in the event of nearby

interference, so a highly directional antenna reduces the
likelihood of interference in the antenna pattern.

• The low power transmitter is intended to be used with a high-

gain antenna for long links.

The antenna requirements are listed below.

Minimum gain .................... 15 dBi
Minimum return loss .......... 15 dB
Connector ........................... N-type
Impedance ........................... 50
