In the upcoming 160M contest, I plan to TX on ANT 1. My RX antenna is about 1/4 wave away (that is as far as I can get it away from the TX anenna)and will likely couple a considerable amount of energ

Good morning, Tim, I have been using receive only, Beverage style antennas for some years now. You are correct in surmising that there is significant voltage on the receive antenna while transmitting

.... A popular device with SWL's is a pair of silicon switching diodes, 1N914 or equivalent back to back across the antenna terminals. The diodes start to conduct at about .25 volts, so usually two i

... A #47 acting as a _fuse_ isn't going to do much. It takes milliseconds to get hot and melt. Your front-end can blow in a few microseconds. If you look at the schematics, you will see that the Ori

Last I checked, silicon switching diodes don't start to conduct until 0.6 volts forward. At 0.25 volts, good diodes have megohms of impedance. If you have 20 volts on a 50 ohm system, you have 8 watt
