Multi-band Antennas 80/40(30)20/17/15/12/10M 

A multiband antenna is based on a transformer that transforms 50 Ohms into a useful impedance for an antenna wire. In this transformation there will be some losses that will heat up the transformer, but this is a normal process in impedance transformation. On high power versions we use external ventilation to cool down the temperature of the transformer. All materials used in our products are high temperature compatible for long term reliability.
