Point1 > You shouldn't lose much if installed correctly. Although the PENTA is a 85cm, if you measure the dish width way, it's 98cm wide.
Point2 > Aluminium would be light in weight and last longer (recommended I suppose)..... but the steel version is still only around 7Kg - 8Kg.
Check my test results on the penta - penta Vs Triax for example
THE PENTA WILL OUT PERFORM THE TRIAX BY A MILE ............
