My comments from the vid regarding the A-Frame would be:
It moves around a lot.
It appears to be made from quite small diameter tube.
The mounting of the Radar high up on the bracket allows its weight to act like a pendulum.
The design with the swept out tubes at the bottom and Right angle joints removes sideways strength which the small triangular plates aren't big enough to put right.
Sorry, just looks like a bad design to me, don't want to offend anyone though.
It was Ok before the radome was fitted. I'm taking the frame off one night this week and then I'll hopefully find a local fabricator to make a more robust up to the job one.
Hopefully won't do too much damage to the cables when I remove them.
