Default Alpha Delta - Balun or not?

News wrote:
Good evening, all.

With no reply from Alpha Delta to my enquiry regarding the benfits of adding
a balun to a stock installation of their DX-SWL Shortwave Sloper Antenna, I
ask of you the same question... is this a no-brainer? Shuild I be injecting
a ~10:1 balun in order to maximize efficiency? I have seen nothing on the
'net to date specifically referring to this design or the merits of
modifying same..

A BalUn is not needed as no part of the system is balanced. A ten to
one transformer is not needed as the antenna is already sufficiently
matched to the feedline.
