- I just built a clamp on RF current meter. Worky worky but I'm thinking about relative levels and how sensitive to make it. I have to think that in a high power ham station it might be reasonable to e

- I built one and never worried about the scale. I had a knob to change the sensitivity. At a certain sensitivity, I would expect all the wires/ cables to have some RF. I only used it if I have a probl

- Hi Martin, This link might help you. http://www.ifwtech.co.uk/g3sek/clamp-on/clamp-on.htm I built one of these and it works great. Good luck! 73 Bert, VE3NR (VE3OBU) I just built a clamp on RF curren

- Not necessarily. Every wire (or conductor) is an antenna, whether we like it or not. A good ferrite choke acts like an open circuit, whereas a poor one (not enough turns) acts like an inductor, and o

- Would this device tell me anything a MFJ-259b or MFJ-269 or other antenna analyzer would not? WOuld the antenna analyzer give better overall context to the data? -- Thanks! & 73, KD4E David Colburn h

- Well I thinking a little more simple than that. I was measuring RF current into a telephone handset. (Remember those, before cordless. Kids that was "Back in the day".) I plugged the filter into the

- Thanks guys, I modelled mine on the one shown on the page Bert mentioned http://www.ifwtech.co.uk/g3sek/clamp-on/clamp-on.htm I'm not so much interested in absolute readings so a pot might be the way
