New product...HF Antenna Isolator


The first of two new products this week.

We've just released a HF Antenna Isolator.

From the web page:

It acts as 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 a risk of electric shock or fire in this situation.

The HF Antenna Isolator also protects the station equipment from static electricity charges on the antenna.
