SP 70 Preamp. switchable 435 MHz

Super effective, Low-Noise-Preamplifiers with VOX

The preamplifiers of the Super-Amp series are available for the amateur radio bands 6 m, 2 m, 70, 23 und 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.

The Super-Amp amplifiers can be operated alternatively with a remote or direct feed. When a power amplifier is used, we recommend our Sequence Controller of the "DCW" product line. This ensures a timely sequential receive/transmit switchover, controlling the relays load-free, without HF.

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.
