There are several possible antenna configurations that can be used for the 915 MHz radio link.
The antenna models allowed on a specific model of CCU or Repeater depend on the unit's
Hardware Version Identification Number (HVIN) printed on the regulatory label. For more
information, see Antennas on page 76. The following list describes some of the possible 915
MHz antenna configurations.
■
A standard vertically polarized antenna (5.15 dBi or 5.5 dBi) directly attached to the collector
or repeater.
■
A standard vertically polarized antenna (5.15 dBi or 5.5 dBi) mounted remotely.
■
A high-gain vertically polarized remote antenna (8.15 dBi) mounted remotely in place of the
direct attached solution.
Warning! Do not install an 8.15 dBi antenna directly on the CCU or Repeater.
Antenna installation directly on the CCU will compromise mechanical integrity and
will not meet the compliance requirement for a loss of 2.2 dB between the CCU or
Repeater and the 8.15 dBi antenna
You must properly ground remote antennas during installation. When a remote antenna is used,
a lightning arrestor is recommended.
Coaxial cable that is used to connect the remote 915 MHz antenna to the collector or repeater
must be properly grounded. For more information, see Lightning Arrestor on page 26. All
coaxial cable connections must be weather-proofed per industry standards, unless otherwise
specified. When the collector or repeater is ordered with a remote 915 MHz antenna kit, some
associated mounting hardware is included. Coaxial cables for the remote 915 MHz antennas are
not included in the kit. The installer must provide these cables. For coaxial cable specifications,
see Coaxial Cable on page 28.
