Fixing methods
Mount the amplifier on a vertical section of the mast below the antenna using the cable tie provided-fig 4
The amplifier will not be affected by proximity to the antenna, but reasonable clearance – about 300mm- should be maintained to avoid
disturbing the antennas performance.
Alternatively, the amplifier can be mounted be methods in figs 5 & 6.
Signal connections
Type-f connectors provide a reliable low-cost method of connection with excellent screening integrity and impedance match. Select the
appropriate male connectors to fit the cable type used, from ‘0.63’ to ‘233’. This method of connection is superior in all respects to saddle-
and-clamp types that it replaces. Good quality coaxial cable to EN50117-2 should be used, ideally to be used in conjunction with high quality
crimp on connectors.
Connectors should be properly fitted in accordance to manufacturer’s instructions, using the correct crimp tool.
F connectors should always be tightened with a spanner. Leaving it finger tight may result in unwanted signal ingress or leakage, as well as
suck-outs in the frequency response.
