well I think I have a problem with the top section. after 60 mph wind gusts the march is high. It's on top of my maco 4 element so I am going to change it out later. Looking at a vertical stick with no ground plane for its a replacement.Too many people I know have had problems with the size and match on the Imax. not going there. Was looking at the gain master but now it's $$ and the two different sizes what the hell? So I went with the old stand by Antron A-99. It works so 99.00 and shipping. around 115.00 us
