Hmmm, mine supposedly is new, but maybe the 420 to 512 MHz version is
different than the other ones since it needs to be adjusted for the band
it's used on. The bottom of mine is just like the diamond but the element is
aluminum put together with the clamps like the ringo, it might just be the
model I have is like that though since it does really have a long way it's
used for and can be adjusted for. Either way, I'd trust it anywhere and
forgetting about it, it's thick aluminum unlike my old 2 meter ringo which
is in my cellar for sale. The tram is about twice the wall thickness.
