HF Antenna Switch
- The purpose of this remote antenna switch was to be able to select between four different antenna combinations The unit was designed to work at RF power levels of around 100 watts by G8JNJ
Antenna Gain to ERP
- A radio's transmitting power can be concentrated along the horizon by use of a GAIN antenna. Although you may still be transmitting with four watts of power, your effective radiated powerwill be greatly increased. This table shows the effects of antenna gain on a transmitter with 4 watts of transmit power.
