CG 3000 Automatic Antenna Tuner

The CG-3000 is a very affordable automatic tuner for shortwave 1.6 to 30MHz, for feeding verticals, longwires, dipoles etc. Like the well known SG-230 this tuner is primarily intended to feed wire antennas or monopoles, the antenna connector is simply a high voltage connector. If you intend to connect coax just connect the shield to ground. The tuner has a tuning range of 12 to 1000 Ω, max. power load is 150W.

Once a setting has been found it is stored in non-volatile memory, so that a new tuning on similiar frequencies happens very fast. The tuner uses a Pi network design which has the advantage (compared to L networks) that is acts as an additional low-pass filter, reducing spurious emissions.

The CG-3000 tuner is operated with 12V DC, other cotrol wires are not required. The solid plastic case is suitable for outdoor use, size approx. 365x240x75mm. U bolts with 55mm width are included. The minimal required antenna length is 2.5m for frequencies of 6MHz and up, or at least 8m for 1.8MHz and up. With a small glassfibre pole (not included) and some wires (not included) a good allband antenna is constructed within minutes.

Covers all HAM bands from 1.8-30 Mhz continuously just using a 8 meters or longer wire antenna.

200W PEP supports most amateur stations.
Easy and quick to tune. 200 memory channels
Solid and robust waterproof housing.
Compact size and light weight.
It can fit long wire, mobile whip, vertical antenna, dipole antenna(without balun), etc.
An affordable and easy solution for you to construct a full band antenna.
