Downside: A high gain antenna can be quite large, require a lot of
expensive aluminum, be quite heavy and like any beam needs a tower
and a rotor.

Since it is truely frequency independant, for certain uses, like military
that could be operating on any frequency, it is an almost ideal solution.

It does sound like it might be viable for portable use, carried in a backpack
to a hilltop. Probably not so good in my back yard though. Too many
buildings, too many things out there already, 12 solar panels on various
mounts, one tall whip, an FM dipole. I can maybe get an extra longwire out
there but that's about it now.

For VHF/UHF, but not for HF.

You do understand that a log periodic is a series of 1/2 wavelength dipoles
from the lowest to highest frequency of interest?

A "small" log periodic that will cover 20 to 10 M will have a boom about
12 feet long and the longest element will be close to 40 feet long.
