The pre-amplifiers of the Super-Amp series are available for the following amateur bands 6 m, 2 m, 4m, 70, 23 and 13 cm.
All models are equipped with super-low-noise, large-signal-resistant semiconductors which are safeguarded against HF by a an effective protective circuit. To suppress unwanted signals, high quality Helix filters are used. With good bandpass filtering strong out of band signals are dramatically reduced or removed.
The Super-Amp amplifiers can be operated with a remote or direct feed. When a power amplifier is used, they recommend their DCW-2004B Sequence Controller. This ensures a safe sequential receive/transmit switchover.
The Super-Amp amplifiers are equipped with an UV-resistant, weatherproof housing and N-sockets. Hot-dip galvanized clamps and installation material are part of the delivery. The max. mast diameter is 58 mm.
