I am rebuilding my HF station after a lightning strike.

I plan on doing a lot of BPSK31/BPSK63 work.

I want to build a dipole optimized for use on 14070/7080 KHz, and 3581 if possible.

These frequencies are not exact harmonic multiples of each other.

A dipole cut for 3581 operating in 20 meters would be 180 khz off resonance.

Would this be too much of a mismatch if I do not use an antenna tuner?

I want to avoid using an antenna tuner.

Would optimizing the antenna for some nearby or intermediate frequency be a good compromise?

Would an antenna just using 14070/7080 be a better solution?


I am located in EM95vs.
What kind of antenna pattern would get from the following antennas:
350-170 degrees mounted 32 feet above ground at center or 60-240 degrees mounted 45 feet above ground?
