Antenna
TRACER is intended to be coupled with an antenna that is directional and provides signal gain. There
are several reasons for this requirement:
are several reasons for this requirement:
•
TRACER operates in point-to-point applications; therefore, an omnidirectional antenna is
not needed.
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.
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.
