[QUOTE="mouse3, post: 772467, member: 350056"] What brand,i don t know,Soviets are classified.I talk with one guy about this subject and show me one photo about. This guys work years ago on theat Soviet interceptor Station with 32m dish. WOW what job,2 weeks maintenace each year and lots of time to test VHF,UHF for fringe using that monster cassegrain. In the 80-th satelite equipment are not allowed for ordinary people like us here in the Est Block. The technology it s here since space age,it s not talking about one new design dish,but they are very well polish like the mirrors for telescope.Polish to microns.If the surface of the dish and subreflector it s very accurate under the microscope the gain increase,87-90%.Here it s the limits of technology. Ask one military dish supplier if you found one to replay about. Flatter dish have the maximum gain,but perform poor to interference.Deeper dishes are used for terestrial relay stations becose have a norow beam.On satellite DX-ing have sense to use them if the interference it s strong and comes from narrow angle.The dish shape must be perfect to escape from interference.One good example it s C band here in towns 3500 Mhz it s permanently blocked by terestrial relay transmission. Search on forum what happens in the Cyprus with 26E transmission blocking BBC signals. [/QUOTE]
