Hi all and HNY.
I have been told that Oscillation in Narrow tuned antennas can occur and make damage to your equipment, radio or amplifier. It is really the first time I have heard about this potential issue. On 160m band, I use a Titanex HD with a matching unit, in fact it is 27.5 meter vertical with a big loading coil at the feed point. 60 ground radials approx. 80 to 100 feet long and two ground rods. The antenna is perfectly matched at 1826Khz. Reason for asking is that I have burned the final transistor in my radio and the final FET`s in my PA is broken. It all happens “out of the blue”. Since I now get a bit worried about this issue, I have installed a sequencer to be sure that my Power Amp, and all my switches and boxes are in time / sync so hope I have done something useful. Oscillation in Narrow band tuned antenna, is this a common issue, how do I avoid it! tune the antenna a bit out of resonance! This is really the first time I have heard about this issue…… any suggestion please.
