New 2m Vertical

Its about time I had a portable vertical for 2m FM work. Now, I do have one, but its extremely heavy! Ive used it on the Clansman masts at the show before, but it takes some serious effort to raise.

So ive decided another Slim Jim is in order. Like the last one, this one will be made from 300 ohm window line, but this time enclosed in the radome of a now defunct Jaybeam collinear.

The antenna itself is now built, and the collinears fibreglass tubing cut to size. However, I have not yet had it on the analyser to see where the correct match feedpoint is. Thats a job for tomorrow.
