Overview

CG Antenna CG-3000 Remote Automatic Antenna Tuner

CG Antenna CG-3000 Remote Automatic Antenna Tuner is an affordable outdoor weatherproof tuner for long wires, verticals, dipoles and other Amateur, MARS or CAP operations between 1.6 to 30MHz. Like the well-known legacy SG-230, this tuner is primarily intended to feed wire antennas or monopoles. The antenna wire connects to the high voltage standoff insulator stud. A UHF female SO-239 connects the station coax and a ground stud may be used for a counterpoise or an earth ground. The tuner has an impedance range of 12 to 1000 ohms with a maximum power handling of 200 watts PEP in SSB mode and 40 watts for FT8 operation. The minimum required antenna length is 8 ft. (2.5m) for frequencies above 6 MHz, and at least 26 ft. (8m) for 1.8 MHz and up. With a small fiberglass pole and some wire, a good all-band antenna can be constructed within minutes.

The CG-3000 Remote Automatic Antenna Tuner is automatically activated with a low power carrier. Low SWR tuning results are stored in non-volatile memory and new tuning attempts on similar frequencies are amazingly fast. The CG-3000 uses a Pi network design which has the advantage (as compared to L networks) of providing low-pass filtering to reduce spurious emissions. The tuner has a 4-pin connector on the bottom panel for the included 16 ft. Control Cable to supply the required 13.8 VDC at 2A (power supply not included). An additional control cable is not required. The solid plastic clamshell case protects the tuner in all-weather outdoor use. Attached brackets and 2.16 in. (55mm) width U-bolts and hardware are included.

An optional CG Antennas CG-CTU Control Unit offers an ON/OFF power switch and a TUNE button, both with LED indicators and a 32.8 ft. (10M) control cable. The CG-CTU includes a 4-pin tuner interface and power connection for Icom transceivers. The CG-3000/CG-CTU combination works with all other transceivers with the included connector cable that serves as a power supply DC cable.
