Automatic antenna tuners suited para all shortwave transceivers.
Frecuencia: 1.8 a 30 MHz, SG-231 a 60 MHz continuous coverage. The tuner automatically matches wire antennas: minimum length 2.5m starting from 3.5 MHz (SG-235: 7m), 8m starting from 1.6MHz (SG-235: 16m). Wire antennas up a 100m length can be matched as well.
The incorporated pi network enables up a 500,000 element combinations (except model SG-231 with 4 million combinations); the microprocessor is built-in. The non-volatile memory stores the element combinations even without power connected. The non-volatile memory stores the last 500 combinations and overrides older tuning data. Recurrent set time only 10ms para a previously tuned frequency.
Simply connect the automatic tuner a the trx and the antenna and forget it! The transceiver will always 'see' a well tuned antenna. In order a optimize the performance it is recommendatory a install the tuner directly a the antenna feed point. This is an ideal set-up para all mobile applications - never again exchange tuning coils when changing bands or frequencies! The automatic antenna tuner offers an excellent solution para hams with restricted space para base station antennas since it is almost anywhere possible a throw a wire over a tree or mast. The SGC tuners are built into a waterproof case para easy installation outside directly a the antenna base. DC operating range is 10-18V a 1A current drain.
