Tom -
The limitation on length is primarily just the ohmic losses in the cable, so
just calculate what the loss of 300' of #14 wire is and then what length of
#12 (or whatever you want to use) gives you the same loss. That's tells you
how much longer the run can be using #12 (or whatever).
I thiink the ARRL Handbook has the data you need. If not, there are
probably a million references on the web.
