Cross Country Wireless HF Antenna Isolator
Cross Country Wireless have released a HF Antenna Isolator for HF and 50 MHz use.
It is a galvanic isolation transformer isolating the mains earth or ground at the station from the antenna or tower earth or ground. This is necessary in areas where PME (protective multiple earthing) is used. Isolating the antenna earth or ground from the incoming mains supply is recommended for electrical safety in case the incoming mains earth or ground has a fault and any mains electricity fault current tries to flow along the co-axial cable to the antenna earth or ground. As the co-ax cable is not designed to handle the high fault current there is an electric shock and fire risk in this situation.
The HF Antenna Isolator also protects the station equipment from static electricity charges on the antenna.
