It's too bad it isn't that simple.
A 1V/m field doesn't result in one volt at the feedpoint of a perfectly matched one meter dipole or monopole, and the value it does induce depends on the quality of the impedance match as well as the fraction of a wavelength the one meter antenna length represents. And, if one volt does appear at the feedpoint, it's very unlikely that a simple circuit will measure it as one volt. Probably best to stick with your $1.5 kilobuck meter if you really want to measure field strength. Roy Lewallen, W7EL Active8 wrote: On 13 Dec 2003 03:50:41 -0800, said... What you are descrbing is a "signal sniffer", not a signal strength meter. Who are you replying to? Paul did not say Signal Stength Meter, but the guy you replied to kinda hints at it when he mentions power level. I would have to say that my 1GHz Signal Level Meter, which cost $1500 would be the better than a relative field strength meter, but if he measures say, 1V with his Tx off and 2V with it on, then that's 1V and if his Rx antenna is a 1m dipole, that's 1V/m.
