Mechanically weak.  Time owned: more than 12 months
I bought my Tonna many years ago (1984) and it worked very well indeed.It was used regularly over a six year period at 35 feet agl,until I had to remove it from service because of structural failure.
The brackets were not long enough to spread the load and stiffen the boom sections.
And the boom section wall thickness is just not wide enough to ensure rigidity and strength.
It (ANT) now lays stacked against my shed as a spare-parts item.
Pity really,as it performed so well.

flimsy  Time owned: 3 to 6 months
good gain,looks good on the mast,good SWR.
poor build quality,lightweight aluminium,stupid mast clamp.
mine snapped at only 6 months old.
OK,it WAS windy,but not that much!!
replaced with a 9ele tonna,same build issues,then replaced with a Cushcraft 13B2

Was good.  Time owned: more than 12 months
Antenna worked very well on 2mtrs ssb, worked the Eastern Mediterranean countries frequently, unfortunately, the winter storms at the end of 2006 saw its demise, it was completely wrecked. I previously took down a very long boom KLM antenna which was sometimes in the vertical polarized mode and survived many similar storms. Such a pity as the Tonna worked so well.
