[Elecraft] A Good Antenna Length?

[Don Wilhelm]

Why do you need a tuner with a well designed fan dipole.  The lengths of 
each set of wires can be trimmed to allow coax feed.

I have 2 fan dipoles here, one for 20, 15, and 10 and another for 30, 
17, and 12 meters.  Each fed with a single coax.
Restricting them to 3 bands simplifies the tuning difficulties 
associated with interaction.  Keeping the wires about 1 foot apart 
reduces that interaction.

I do not mix bands that are 3rd harmonic related on the same coax, it 
just complicates things - in other words, I do not mix radiators for 80 
and 30 on the same coax, the same for radiators for 40 and 15 meters.

The KISS principle applies.
