Hi. I have an transmitter at 160m band (500w). i know that when the weather is bad, the antenna's wire (inverted L) has a voltage about several kvolts. I would like to protect my transmitter. I am th

My guess is that your transmitter should be the least of your concerns. I'd be much more worried about your receiver. A good voltage drain will not only protect your equipment, but also reduce the no

A good RFC between the antenna feed point and ground will take care of any voltage build up on your antenna...It won't stop a lightning discharge from getting into your equipment though if you have i

I agree with Rob's suggestion that you look at the ICE products. I also use them where the feedline enters my house at the entry panel (with single point ground). When properly installed, they provid

tzitzikas_ee  et al:  (grasshopper or cricket in Greek?) While I agree that an RFChoke to ground can help drain static and a lightening surge protector is also a very good idea, nothing outperforms t

I agree, George, that a manual disconnect is the best way to avoid damage. But I wouldn't consider leaving out the resistor or choke. One evening many years ago, I was listening on 160 with a vertica

A quarter wavelength shorted coaxial stub across the feed point provides a DC path to ground and greatly attenuates differential-mode lightning current. Dave WX7G ____________________________________
