VHF ANTENNA INSTALLATION

The VHF antenna is an important part of the receiver and transmitter system;
the reception range is heavily dependent on the antenna installation.

The VHF antenna must be installed as high as possible and free of shadow effects
from the buildings and trees; effective installation will maximize the range of the system.

The poor installation of coaxial cables/connectors (and as effect the high VSWR)
may cause the transponder to shut down.

Mounting of VHF antenna:

VHF AND GNSS ANTENNA CABLE CONNECTIONS

The VHF and the GNSS (GPS, GLONASS/GPS) antenna cables are connected
directly to the T124 unit through UHF and TNC plug respectively.

Recommended cables to be used for VHF\GNSS antenna connection:
