Glad the Radar-Rama is working for some - mine was missing srews, clamps, and still had metal shavings from the factory in the bag. After less than a month I found the screws rusted (in southern California USA where it had not rained in six months) and the ground plane stubs weather seals are just rubbish.
The paint started flaking off of the center aerial too - at this point I replaced it with the DPD Productions antenna here in the US and coverage was much better.
Maybe I just got a bad RadarRama but it sure looks and feels very poorly made.
