    C h a p t e r 5 Practical Installations At SGC, we get calls everyday, asking if the Smartuner will tune a particular type of antenna. The impedance matching range of the Smartuners is from about .1 Ohm to 10,000 Ohms. As long as you follow the basic guidelines and use good practice, you can expect the Smartuner to match virtually any load to your transmitter.
