automan4025,
I guess it just depends on what you call 'real big'. Something on the order of 8 x 18 feet certainly sounds big but is actually pretty 'small' for an 11 meter directional antenna. That's just a 'ball-park' number, not particularly accurate for size, but close. It would be sort of accurate for maybe a 3 element beam. A two element beam would change that 8' to something like 3 or 4 feet. You're pretty well 'stuck' with that 18' figure, sort of. Is that 'small' or 'large'?
