The claims and actual measurements for both versions of Q82 are as of recently only available on wayback machine Eddie,
looking at the Q82mk1 you will see that they call it a .82wave but look further down at the antenna height @ 27.500,
its only a tad longer than a Nv4k and it has fatter radials at the same spacing
making it look a little shorter electrically,
it is not a 29ft+ .82wave antenna on 27.500mhz as claimed
The mk2 comes in two versions,
version 1
has a 10" shorter monopole than the mk1,
it has a 3/8wave cone with 1 set of spreaders up near the hoop,
the hoop is 3" smaller in circumference than the mk1
version 2
Had a modified taper schedule using longer 38mm & 30mm lower monopole tubes so that the upper spreader clamps to a larger diameter tube & a second set of spreaders were added lower down to keep the long radials more accurately spaced to the monopole in wind,
regardless of what the advertising claims none of them are .82wave antennas on 27.500mhz.
