SGC Tuners

MAC200

1.8MHz - 54MHz 200W

•  commercial quality
•  auto ATU (200W)
•  1.8MHz - 54MHz
•  matches almost any antenna including: G5RV, dipole etc

Select the right antenna, for the right band, at the right time with the MAC-200. The Master Antenna Controller operates as your base station control center, eliminating complicated switching and tuning. With the MAC-200, you can select between up to five antennas and tune automatically to minimum SWR. You can monitor your power and SWR with two convenient meters on the front panel of the unit. The MAC-200 puts you in control of your antennas.

With SGCs Smartuner technology inside, the MAC-200 uses two built in microprocessors to automatically select the correct antenna for your operating frequency, quickly and accurately. It stores the correct settings in memory and will recall the settings for a previous frequency in less than ten milliseconds. The MAC-200 is the perfect choice for anyone using multiple antennas in a base station system.

The SG-230 Smartuner was the first product in the HF market to offer fast, flexible tuning without any user interface. The Smartuner senses RF when you transmit from your transceiver and automatically finds the best SWR match to your antenna. This unit works with ANY radio and ANY antenna and requires NO special interface, making it the most versatile tuning product available. The SG-230 can be used in base station, mobile, marine and aviation applications - and has been the "Gold Standard" of automatic antenna tuning for more than a decade.

The SG-230 is built in a rugged ABS plastic enclosure which is sealed to protect it, and allows ultimate versatility in installation. With this tuner and any single antenna, you will have continuous coverage from 1.8 to 30MHz and it can be used with any transceiver you'll ever own. The unit is built to last, with the highest quality components and backed by SGC's standard 1 year warranty and industry leading technical service.

SGC231

HF + 6m SMART ATU

•  HF + 6m auto ATU (100W)
•  1.8MHz - 60MHz

A further refinement in the ability to tune almost any radio and any antenna with more discrete tuning components and microprocessor tuning power

SGC237

HF + 6m - smaller version

•  HF + 6m auto ATU 3 to 100W (PEP) and 40W (continuous)
•  1.8MHz - 60MHz

The SG-237 is designed with high density surface mount components on a 4 layer PCB, providing high efficiency, reliability and performance. The PCB is mounted on a sturdy chassis plate which provides an excellent electrical and RF ground system. The unit is fully waterproof (under 2 ft of water for 24 hours). The case is weather resistant, high grade ABS plastic that is sealed at the factory.

The SG-237 is our most popular Smartuner. It's rugged construction and small size allow maximum flexability. It has a 100W power rating and additional frequency coverage to 60MHz, matching it perfectly with the most popular HF transceivers. It will work with any balanced or unbalanced antenna including whips, backstays, dipoles, loops and longwires, and requires a minimum of only 28 feet of antenna for full coverage operation.
