SGC Smartuners deliver more flexibility and accuracy than any other HF antenna coupler on the market. They are independently intelligent, matching any HF transceiver and any antenna, with no user interface. Smartuners are available in power levels from 1.5 to 500 Watts and frequency ranges from 1.6 to 60 MHz. They provide efficient, accurate, all purpose tuning that is ideal for base, mobile, portable, marine or avaition. An SGC Smartuner ensures that you will get the most efficient, most accurate tuning solution possible.

Smartuners are CE Certified(pdf).

The Smartuner requires no special interface to work with any transceiver. Simply supply power to the coupler, connect your antenna and ground system, hook up RF from the transceiver and transmit. The Smartuner will sense your operating frequency, find the SWR and create the best possible match (typically less than 2:1). There are no buttons to push or knobs to adjust.

Smartuners do not require an antenna to be resononant on your operating frequency. Any antenna that meets the minimum length requirement will allow for continuous coverage within the coupler's frequency range. This gives you complete freedom to operate across multiple bands with a single antenna.

When you change frequency and transmit, the Smartuner will find the best match for your conditions in less than 5 seconds. If the coupler has been on a frequency before, it has stored the solution in memory and will recall the match in less than 10 milliseconds. Since the memory is non-volatile, the Smartuner will remember your most used frequencies even when powered off - even for years.
