[TowerTalk] Looking for a light coaxial

[Jorge Diez (CX6VM-CW5W)]

Hello

I am looking for a 50 ohms legal limit coaxial, but a light one, for a wire yagi

I am using 213 hanging from DE, but it’s too heavy and stress too much my rope boom 

Maybe a coaxial with center in aluminum? Or something lighter than cooper

Thanks!
