the P412 to a power meter. The maximum level shown in Figure 12 (-13 dBm at a gain setting of
63) corresponds to the maximum level permitted by FCC when used with the Broadspec antenna. It
is not possible for the user to enter a value greater than 63. Using any antenna other than the
Broadspec invalidates the certification.

7 Broadspec Antenna
The P412 is designed to operate with the Broadspec P200 antennas shown in Figure 13. Use with
ANY other antenna invalidates the FCC certification. Per FCC 15.203, the Broadspec antenna must be
professionally installed and the installer has the responsibility to insure that the Broadspec antenna is
used.
The P412 can be operated with a single antenna (used for transmit and receive) or with two antennas
(where one is dedicated for transmit and the second for receive).
The Broadspec Ultra Wideband Antenna (~3dBi) provides an omni-directional transmit/receive
pattern supporting a frequency range of 3.1-5.3 GHz. It has a standard SMA female connector and
measures 1”x 2.5” x 0.125”. Specifications available on the web at:
