If the current is unbalanced, this would mean current is likely to flow
on the coax then? So perhaps the reason a voltage balun is used is to
merely transform the impedance 6:1 and purposely allow the feedline to
radiate? The maker of the antenna (Buckmaster) doesn't indicate any
particular length of 50 ohm coax be used, but I saw a huge change in
SWR and bandwidth on the upper bands when I lowered the antenna by 5
feet. Maybe this explains the behavior I saw.
