Primesat 1.8m prime focus satellite dish.

Primesat P18MOT 1.8m prime focus motorised dish. At last a high gain high quality prime focus dish.In the early days of satellite most dishes were prime focus. These days most dishes are offset.This is two ways of doing the same job but prime focus dishes point upwards and look purposeful.From the appearance point of view they are usually the enthusiast's favorite. This one ismade of aluminuim and is one piece. (As a general rule, aluminium is preferable to steeland 1-piece tends to be more efficient that "petalised" or segments.) This attractive dishcomes complete with a very heavy duty polar mount, a prime focus Invacom adjustable feedhornwith Primesat yellow cap and Invacom LNB. The polar mount is "dipped galvanised" which is the best possible type of treatment for withstanding corrosion in high salt areas. Everything about this dish is high quality. All of the nuts and bolts are made of stainless steel. The elevation adjusters are made of brass.Also show in the picture is an optional Primesat GS76125 ground stand.
