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?

Good morning,

Jamie, N2VJ, reported this morning on SLACK that a US-based company is
producing a portable, turnkey 630-meter vertical antenna system.
Originally developed for BC medium wave AM as an emergency continuity
system, this model has been modified for 472-479 kHz. You can see the
specs here: https://theradiosource.com/products/antenna-630pd.htm

Jamie indicated that the company is probably testing the market and
the price may be somewhere in the $890 USD range. While that may seem
pricey to some, there are a lot of people out there still waiting for
a turnkey option and engineering and materials are expensive these
days. Yes you can build this stuff for a LOT cheaper but there are a
lot of hams today that can't or won't so here is an option to fill the
void.

Have a look and show some interest as doing so often drives product
development and innovation.

Jamie explicitly noted that he is not endorsing this product and he
has no financial interest.

73,

John KB5NJD
