antenna coil forms

I think they can be sent parcel post without any wrapping....I'll just stick a mailing label on them and send them out. When it arrives just look at the postage sticker and reimburse me that amount. Any takers? If so, email me (off list) your name & mailing address. 72 & Regards, Rich k2cpe K2 #1102 Tempting, but I'm in pretty good shape here I guess. Also, I'm kinda wary of any paper material, as it might get damp, etc.. I'm always looking for things to build antennas, coils, etc... I just stumbled across another recently... I've been thinking about making a "plastic bugcatcher" for 160m. I already have two 80-10 versions.. But I always was wondering what to form a bigger coil on...Well, I think I found one way... Use these big canisters that DVD's come in... I torch up a lot of DVD's, and buy a lot of them. Both 50 packs, and 100 packs, that come in the big plastic canisters. I was looking at one the other day, and thought, *dang*, this would make a pretty good coil form... They are 5 inches dia, and about 6 inches tall, if you used a 100 pack.. They already have a spindle running through the middle as an alignment guide.. Some thin sticks might fit as is, but most would need to have that widened out a bit.. Would be a cinch to rig up.. So I think I'm going to use one of those to wind a 160 coil. yep, it will be heavy with the wire, and the antenna would have to be guyed when driving I think. But I could use as is sitting still. Those canisters could be stacked for more height. The coil on my 80-10 antenna is 3 inch dia plastic tube, and the top and bottom caps were peanut butter jar lids. They fit perfectly. I drilled holes in the caps, and ran the stick up through the middle, and then glued and sealed it. MK |
