I had been using GP8 for a long time. Last year I had to take the vertical down because of roof repairs. It's in a good shape but sometimes after heavy rain, there is a problem with SWR on some bands. Maybe some of the traps are not completely waterproof after all the years. Last year in the middle of July I wrote an email to Waldek SP7GXP if he can send me the new vertical by post service. He wrote me, that they will have a new version of the GP7DX vertical in September and I have to wait.
