elements can be connected at the same time, but I think it's more than the
two I have up there now. Richard gave the number five. That's why I said
I'm going to try a set for 40m.

A fan dipole with elements for 40m and 15m doesn't
work well because of the resonant interaction
between those two elements of 0.5WL and 1.5WL.
Most hams I know use the 40m dipole also for 15m
operation with a tuner.
