[600MRG] "The Lowdown Amateur Radio Antenna for 630 Meters Model 630.PD"

[Greg KF5N]

I like the design as I could use it even in my relatively small back yard.

The availability of a turnkey antenna and other gear is good, but I'm not
even sure there is that much easily available reference material if you
want to build your own.
I recently ordered the 2022 ARRL Handbook, and found only one page on LF
propagation.  Did I miss something, or is there no other information on the
ham LF allocations in the latest handbook?

Let's say I was a newbie interested in trying out 630 meters.  Where would
I go to find construction details for an antenna equivalent to this
commercial offering?
Long ago (1980s) I built and operated a Lowfer Beacon.  There was the
series of books by Ken Cornell, and a couple of enthusiast periodicals on
Lowfer and other LF topics.
Lots of antenna topics and construction articles in those publications.
Is there something equivalent to this today for 630 meters?
