Is there much one can do for sensitive electronics? For example, during the
summer at my QTH, late day thunderstorms are common and on one such day I did have the antenna disconnected from my Drake R-8B but a FET still managed to get fried and I needed to send the radio back to Drake for repair.

And at least there is NO insurance it will work under ALL circumstances. Best (additional) way to go is to disconnect the antenna when leaving the shack or lightning is coming up whilst you are in your shack. Not true. You have to be anal-retentive as hell to make sure that it is done right, but you can do it properly using the right equipment. Polyphaser or I.C.E. protectors do the job well, but they must be mounted on an appropriate ground window. The object of the game is not to have your equipment at ground potential; rather the object is to have the potential on all the equipment rise and fall together so there is no differential amongst the equipment. There is quite a bit of introductory material at www.polyphaser.com. Eric -- Eric F. Richards, "Nature abhors a vacuum tube." -- J. R. Pierce, Bell Labs, c. 1940 |
