Recieving antenna : voltage estimation

Hi everyone ,
i am asking if there is any way to deduce the voltage across recieving antenna terminals , supposing that we know the waveforme submited to it as well as tha distance and all neded parameters of the two antennas ( transmetter and reciever) ?
please could anyone help me ?
thanks ,
 

Re: Recieving antenna : voltage estimation

A crystal radio set is powered by its antenna. It generates sufficient voltage to overcome diode threshold. This assumes the broadcast is strong enough to pick up.

There may be a formula to predict theoretical performance. Perhaps it has to do with quantity of photons leaving the broadcast antenna, along with ability of receiving antenna to pick up photons. There are other variables in the selectivity and sensitivity of the receiver.

I've seen specs for a receiver in the 1 uV range. It suggests that is the minimum voltage needed to drive the pre-amp. Perhaps it's merely a marketing spec. I could be wrong.

thank you BradtheRad ,
crystal radion can not dispass certain levels of voltage ? so the voltage to submit is limitted in range ?
