[QUOTE="guest poster, post: 577875, member: 262401"] The 2.4m Andrews ASC is about £2500-3000 plus floor mount/pole... so you can see the attraction of the £170 2.4m or £100 1.8m. If you go for a used one, the face on the ASC 2.4m is in two halves and even with the price 'they' are often put together wrong. If they are bolted up twisted, the shape is pulled out, in the hot Med sun, that could be permanent even if a professional comes along afterwards to sort it out.. it may not be possible and has thermally reset in the hot sun. The tolerance is 0.25 inch or .6mm (max out) on the 2.4m's seam. The bolting procedure and torque settings are critical too, and if that's not followed either that can spoil a dish too. Very few have the equipment to test the parabola's tolerance of dishes that size. I think you could set up a 1.8 fs accurately and then strengthen it, with the right lnb/feed horn you'd match the C M. not sure about doing the same with the 2.4 fortec star... turning it into a decent dish could cost too much.
