i tried recently to make cantenna with pringles tube but i think the problem was with the active element the conductor i think its bad conductor
i tried with NetStumbler and saw the graph of the signal always when i put on the copper gives bad signal and when i put on the small conductor golden copper that came out with the RP-SMA it gives good signal !!
any one have any idea where to get good copper element quality to conduct my signal from the pigtail cable ?
