The FCC specifies the maximum transmitter power that may be
used for antennae of a given gain. FCC rules Part 15, Subpart 247
allow for a maximum power of 1 watt into antennae of a gain less
than or equal to 6 dBi. For every 3 dB of gain over 6 dBi, the
transmitter must be reduced by 1 dB. The following table lists the
maximum transmitter power for given antennae gains.

The transmitter power is set by way of a potentiometer on the
front panel of the BBP or via the configuration page of the interface
VT-100. The RFC must be attached by way of the IF cable during
this operation. Attach an RF power meter to the N-type antenna
connector on the RFC, and adjust the power by way of the
potentiometer or VT-100 until the desired transmitter power is
obtained. For convenience, the transmitter power adjustment
should be made before the RFC is installed on the mast.

The frequency plan designates on which frequencies the Tracer
transmits and receives. Plan A corresponds to a transmitting (Tx)
frequency of 2422 MHz and a receive (Rx) frequency of 2462 MHz.
Plan B corresponds to a Tx frequency of 2462 MHz and a Rx
frequency of 2422 MHz. Shipment of a link consists of one RFC
set to Plan A and the other set to Plan B unless specified otherwise.
The RFC plan can, however, be changed in the field if required.
This procedure involves two steps:
transmits and receives. Plan A corresponds to a transmitting (Tx)
frequency of 2422 MHz and a receive (Rx) frequency of 2462 MHz.
Plan B corresponds to a Tx frequency of 2462 MHz and a Rx
frequency of 2422 MHz. Shipment of a link consists of one RFC
set to Plan A and the other set to Plan B unless specified otherwise.
The RFC plan can, however, be changed in the field if required.
This procedure involves two steps:
• Configuring the RFC interconnect
• Informing the BBP of the correct Plan
• Informing the BBP of the correct Plan
