along wth the cost, its kinda academic to discuss optimal cans. For example,
although the Home Brew can is better spec'ed, the Milo (medium size one) tin
works the best of all Ive made. (Ive estimated up to 10 - 14db gain, though
Id never put money on that being accurate, its my best effort with
netstumbler and comapred against one commercial yagi.)

and unless you are trying to do many km's, most should be fine. Ive had mine
working at 4kms full speed, and have been able to netstumble from 8kms with
NO LOS at all. (behind and below the peak of a hill.)

at the right length, and I think this is as big of a factor as the can size.

> I guess my point is, dont wait for someone to tell you what the best can
is, just go get some of the gear and make some! (I should also point out the
first one I made was the best...!) Most everyone has a Milo or Coffee tin,
and if you brew those 1.7kg coopers brews, then your set!
