Automatic mast antenna tuner

Automatic antenna tuner

The CG-3000 is a reliable automatic HF tuner from 1.6 to 30MHz, for uprights, longwires, dipoles etc. Like the well known SG-230 this tuner essentially it tunes filter antennas or monopoles, the antenna connector is simply a connector high voltage. If you intend to connect a coaxial, first connect the screen to the mass. The tuner has a range from 12 to 1000?, max. load power:150W.

Once the agreement has been found, it is stored in a non-volatile memory, so that a new chord on a similar frequency will be very fast. The tuner uses a Pi network which has the advantage (compared to the L network) of acting as a filter additional low-pass, reducing spurious emission.

The CG-3000 tuner operates at 12V DC, no other connection cables are required. The sturdy plastic container is also suitable for outdoor use, dimensions approx. 365x240x75mm. The minimum required antenna length is 2.5m for frequencies from 6MHz and above, or at least 8m from 1.8MHz and above. With a small fiberglass pole (not included) and some wire (not included) you can build a good antenna for all bands.

Pi matching network

CG-3000 is designed with Pi matching network. It provides more wide tuning range and covers whole HF band. Using 9 solid inductors, the total inductance ranges from 0 to 32 uH. They can give 255 combinations with a resolution of 0.25 uH. 5 capacitors are used at the input side, the total capacitance ranges from 0 to 6300 pF with 31 combinations. Other 5 capacitors are used at the output side, the total capacitance ranges from 0 to 755 pF with 31 combinations. So totally they give 245055 tuning combinations.
