Oh, I doubt it.  I put them up in ... 2010?  I did find and print out the 
docs, so the measurements were correct at time of install.  IIRC, the SWR 
on 2m was OK at that time.  No way of checking 70 cm, but radio did not 
catch fire when used.

They are a little ... overwhelming ... mounted on the side of the house so 
I'm seriously considering selling them (and the Channel Master wall mounts) 
and replacing them with that Arrow Antennas dual-band ground plane that was 
in the Jan QST.  I have 10 elements for DX; these or the GP are just for 
local repeaters.
