Digilink MK3, USA Mains Version

Other Antennas

In addition to the standard BNC mount 1/4 wave antenna (UHF14BNC), which attaches directly to the
Connexions transmitter, 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.
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
(FDANT).
Pre-terminated coaxial feeder cables are available for 5, 10 or 15 metre requirements. Consult your
dealer for further details.
Note ! Only permitted for use with the above Scope approved antennas, all of which are zero Db
gain. 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 your dealer's Technical Department.
*subject to license conditions. Specifically, mounting height and Effective Radiated Power (ERP).
