The BuxComm Antenna Company sells what it calls an All Band Coax-fed
Dipole.

It consists of 135 ft. of wire, a balun at the center feed point, and
the RG 8X coax transmission line.

A true coax fed "dipole" needs to see a 50 ohm load on
any of the bands to be used. Well, unless you like to lose
a lot of power on some bands. :/ So it would be better to
use an auto tuner at the feedpoint. It would be even better
to decide what bands you *really* intend to use, and run
dipole legs for each band in parallel. Spread wide apart
is better than stacking them on top of each other with
spreaders.
The antenna as they sell it is pretty micky mouse for an
"all band coax fed dipole". As one mentioned, the loss on
40m could be large if you feed with coax to a high Z load.
The antenna they sell would be best run using ladder line
all the way to a tuner, or tuned by length. Seems like you
say they mentioned this, but then why buy the uneeded
coax, choke, etc that you would end up discarding. ??
