I am talking about the antenna in this months QST page 38 ZS6AAA

"The Compact Quad Multiband Hf Antenna" August 2006

So i hope i have not crossed wires here. But this antenna is open wire
fed, supported on a single fibreglass pole.

Hi Pat

Actually the "Compact Quad" is meant to be fed by 50 Ohm coax through a
1:1 balun attached at the end of the open-wire matching section. Here
the VSWR should be under 5:1 on the 40, 20, 15 and 10m bands. Of course
you can also use open-wire line, but then the VSWR at the radio will
depend on the length and characteristic impedance of the feed-line.
