WOLF RIVER COILS

With more than 70 years combined amateur radio experience, Gary KB9AIT and Terry N9AOT developed a high-quality HF antenna coil that is easy to use, easy to install, easy to maintain and easily changes operating frequency... Hams can conveniently operate mobile, portable or fixed-station. WSPR studies at only 0.2 Watts transmission power show that Wolf River Coils work well. Here is an example of a 24-hour WSPR study on 20 meters... We build quality antenna coils that are easy to install and easy to tune.
