Now lets talk about antennas. It isn't likely that we will have single
antennas at any station, save for the resurrection of the old general
purpose dipole fed with ladder line, run through a tuner. That's one
that olde tyme hammes will recognize! I suppose the Steppir antennas
could work if you have enough coin. The method proposed by Jim will not
accommodate the tricks we use now to provide an acceptable match as the
major HF bands will not be harmonically related.
Trap dipoles don't have to be on bands that are harmonically related.
Not if the passband you want to operate on falls within the other
desired band. In most cases you still need a tuner for bands other
than the ones the antenna is cut for.
You noticed that too?
I'm waiting for the specific frequencies Jim is thinking about, so I
can design a multiband antenna for this idea.
I suspect I'll not be too successful.
Maybe some others might have more success. Hopefully they will share
their design with me.
