On receiver side, after the UHF module has been secured to
the receiver and properly configured, do the following
whatever your choice of antenna setup:
• Pass the male connector of the coaxial adapter cable
(PN 96845) through the oblong hole of the pole extension
(PN 95672) and make it go out of it at its upper end (see
[12]).
• Connect it to the coaxial output of the UHF module.
• Screw the pole extension to the threaded part on the UHF
module (see [13]). Spin the pole extension, rather than
the receiver, taking care not to jam the coaxial cable
extension when doing this.
• Secure the receiver/pole extension assembly onto the
tripod.
• Connect the other end (female connector) of the coaxial
cable extension to the coaxial cable coming down from the
UHF antenna.
• Set up the base on the chosen reference point.

Radio Setup With
Internal UHF
Antenna
The UHF antenna is connected directly to the UHF module
and is hidden in the pole. The pole is installed on top of a
tripod. Follow the same instructions as with a rover (see
Completing Rover Radio Setup on page 49) to install the
internal UHF antenna, but this time you will be using:
• A quarter-wave antenna (P/N 67410-11 or 67410-12,
depending on the frequency band used) instead of a half-
wave antenna. This shorter antenna is available as an
optional accessory (see Other Optional Accessories on
page 4).
• The pole extension with the oblong hole (from the UHF
option kit). You don’t need to use the coaxial adapter
cable.
