SCPUHF Paging Transmitter System

Other Antennas

The range and performance of this equipment can be improved by the addition of more efficient
antennas*. These can be installed either inside or outside the building and are connected to the
transmitter with 50 OHM coaxial cable.
Glass mount antenna (UHFGM): for installation on the inside of a suitable window. This can boost
range, especially if it is required in one direction from the building.
The centre fed half wave di-pole, measuring approximately 12 inches from tip to tip, will provide
excellent all round local signalling. This can be mounted either inside or outside a building. Two
versions are available:
1) a light duty antenna suitable for sheltered environments/internal installation (LUHFDP).
2) a heavy duty stainless unit with optional mounting hardware for more arduous applications
(UHFDP).
The 6dB end fed colinear (UHF6DB): for external application. When elevated, this will boost overall
range at a slight loss to some local signals.
Pre-terminated coaxial feeder cables are available for 5, 10 or 15 metre requirements.
Note ! High frequencies can equate to high power losses. Always use quality cable. RG58 is only
acceptable on cable runs of up to 5 metres. We recommend RG213, or equivalent, on greater
lengths. If in doubt consult our Technical Department.
*subject to license conditions. Specifically, mounting height and Effective Radiated Power (ERP).
