Presumably you are aware it's illegal, and could cause interference for hundreds of miles?.I have a signal genny which can generate FSK which I intend to plug an antenna into if I can find one.
I also have a copy of MATLAB/SIMULINK with an SDR which I hope to use to view the spectrum of the FSK.
I would think the power would be in the order of a few hundred milliwatts at the most.
Such powers and frequencies have been used to transmit across the Atlantic, it goes a LOT further than you might imagine.I didn't think at such a low level, the signal would have travelled that far or cause interference.
Then you do not need an antenna.I would like to have a fairly accurate idea of the power I am transmitting.
OK. In this case, you can fabricate a simple quarter wave monopole out of some wire, and a length of coax to attach to your signal generator (with appropriate connector). If you decide to go this way, we can give you some dimensions, which will depend on frequency.Although it is only testing/experimenting, I would like to have a fairly accurate idea of the power I am transmitting. I know I can get this from a matched antenna, not sure about a variable length of conductor.
