My antennas are all within 15 feet of each other. W7WW's are
within 8 feet of one another on a single 70 foot crankup. We
both run high power. SO2R is definitely do-able on a small
lot, or even on a single tower.
I suggest a Steppir triband dipole above your C3E. The
Steppir won't mess up the C3 because it will always be set
for a different band. The tribander won't affect the Steppir
much, because the Steppir is just a dipole. Use the Steppir
for S&P and the tribander for running. A nice straight
dipole at 65 feet is plenty loud enough for S&P. If you have
trouble getting through with the dipole, you can flip the
6-pak. In fact, I've got a position on the 6-pak switch that
will flip the big antenna to the active radio (driven by the
A/B signal on the computer's LPT port).
