Would their be a big difference if the 'flat top' has two runs of
3/8 aluminum cable side by side spaced about 30 inches ?? or
would one 3/8 cable do the job???

Thank you for your input

The combined "resonant length" is almost the same with the two.
Appx 215 feet total radiator for the short one, vs appx 220 ft total
for the tall one.. I would go for the tall version myself.
Either one will still need more coil loading to tune.
