| I use a Cushcraft R7 vertical as my HF antenna. Only problem when I bought it, it has the 20m trap and then a top peace, that I presume is 'AF', so its missing the 30m trap and 40m section.|
I was told I could add a piece of Aluminium onto the 'AF' piece and then be able to tune for 40m, however does anyone know what length I should add on?
