Hi
Call the 800# and ask for the radials for antenna 20-043. I believe they don't sell them seperately. It would come as a radial rod kit.
I think there was a post already regarding this a few months ago and mention this.
Take care
Consider replacing the element(s) with 3/16 aluminum rod and tap the hub for #10-24 (I think). I replaced all the flimsy elements on a RS Discone and am very happy with it now.
