Following http://www.pa3hcm.nl/?p=650 I am going to basically try and create a short 23cm antenna on a Ali boom using welding rods and a length of 6mm copper tubing (was from an A/C unit I think).
I will use a copy of the DL6WU spreadsheet I have from previous as that site's link doesn't work now.
Copied from that site... I'll basically use materials I will either have to hand or will get. YEs understand 1mm out on the length is MHz so test of my skills.... Semi rigid hardline I have a few options for the matching section.
