Or else just use small diameter rigid tubing. Agreed. I'd be tempted to try brass tubing, available from good hobby shops - it's light and rigid. There are some very effective DF/foxhunt antenna designs on the Web for which the elements are pieces cut out of a scrapped steel measuring tape. The material is light, quite stiff when it snaps out into shape, and can survive numerous whacks and bends without suffering permanent deformation. I'm sure its electrical losses are a good deal higher than for copper, but unless you're DF'ing really weak signals I doubt that this would be a problem. Just make sure you put some sort of protective coating or cap over the cut ends... they're sharp and could easily scratch / cut / put-out-an-eye! -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |
