I have an analysis up at


The problem is the antenna is too short for the lowest band.
88 feet is too short for an 80 meter dipole, 44 feet is too
short for a 40 meter dipole.

I disagree. A nice pattern isn't nearly as important as
being able to apply power to the antenna. The problem is the
antenna is too short.

I would think being able to tune the antenna with a tuner is
a basic requirement of any antenna, backup antenna or not.
