[Antennaware] Feeding transmission lines with a common source

[n4zr at contesting.com (Pete Smith)]

I would like to be able to model the situation where two antennas are fed 
through transmission lines from a common source, but am having trouble 
figuring out how to do that in NEC-2.  I tried using a short wire, apart 
from the model itself, with the source in the middle and one transmission 
line connected to each end, but am getting error messages from MultiNEC 
that something is wrong in the transmission line definition.  According to 
the EZNEC documentation I have, this should work, but it doesn't.

Any suggestions much appreciated.
