SG230 Smartuner, antenna tuner f. wire antennas 1,8-30MHz, 200W, weatherpr.

Frequency range: 1.8 to 30 MHz. 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 to 100m length can be matched as well.

The incorporated pi network enables up to 500,000 element 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 for a previously tuned frequency.

Simply connect the automatic tuner to the trx and the antenna and forget it! The transceiver will always 'see' a well tuned antenna. In order to optimize the performance it is recommendatory to install the tuner directly at the antenna feed point. This is an ideal set-up for all mobile applications - never again exchange tuning coils when changing bands or frequencies! The automatic antenna tuner offers an excellent solution for hams with restricted space for base station antennas since it is almost anywhere possible to throw a wire over a tree or mast. The SGC tuners are built into a waterproof case for easy installation outside directly at the antenna base. DC operating range is 10-18V at 1A current drain.
