Antenna Selection

TRACER is intended to be coupled with an antenna that is directional (thus providing signal gain). There are several reasons for this requirement:

•TRACER operates in point-to-point applications so omnidirectional antennas cannot be used.

•The low power transmitter is intended to be used with a high-gain antenna for long links.

•Directional antennas minimize the interference that a site is susceptible to and also minimize the site’s interference to other sites.

The antenna requirements are listed below.
Antenna	100 mW	1 W
Minimum gain	15 dBi	6 dBi
Minimum return loss	15 dB	15 dB
Connector	N-type	N-type
Impedance	50Ω	50Ω
