[Antennas] Sandpiper verticals?

[Richard]

Hi fellow hams!

I am considering a Sandpiper Mini-Delta but want to complement it with 
something for 30/40/80 and perhaps 160. Sandpiper makes the V and MV series, 
anyone out there using one of these? Any pictures of an assembled one?

I am particularly interested in the V5+3 MKIII or the V9 MK III or perhaps the 
(M)V10, but I can only find a drawing on their site, no pics :-(
Any things I need to consider?  I assume they are auto band switching, any 
comments on that? How do they perform in every day use? I want to roof-mount 
it, anyone use it that way?

Lots of questions, hope someone on the list can help.
