[QUOTE="Vipersan, post: 978917, member: 325666"] Today I thought I'd have a crack at making a quarter wave dipole centre frequency around 129 mhz for Airport coms etc .. So ..a combination of plastic plumbing and 15mm copper pipe with capped ends ...and a homebrew balun on the support bar .. Pics are below .. not tested as yet ..but I am hopeful.. The tricky bit was reducing the 22 plastic overflow T to carry the 15mm copper elements ... This was done with my old friend liquid plastic [ATTACH=full]95498[/ATTACH] rgds VS [/QUOTE]
