7.RX Antenna Connector
Both the 3 dBi omni-directional magnetic mount antenna (Figure2 on page 4)
and the 11 dBi high gain patch antenna are attached at the RX ANTENNA BNC
connector.
Use the patch antenna with the Mafer clamp whenever you can reasonably
expect the wired agentto be within a known general location, such as a
particular street corner.The patch antenna is quite directional with a beam
width of about 60°. With thepatch antenna you will receive at a greater
distance than with the omni-directional magnetic mount.
When using the patch, orient it with the Plexiglas side facing toward the
expected location of the transmitting bodywire.
CAUTION Patch antennas are directional. Always orient the
RXpatch toward the TX. On a surveillance mission,
the agent should take care, within bounds of security
and safety, to be oriented with the TX patch antenna
outwards from the agent’s body and facing the RX.
TIP Mount the RX patch antenna as high as possible to
provide a better unobstructed path to the TX.
