  • My shack as seen once in a blue moon! Took me ages to put things nice and neat!       Phew ... no more pictures !

 
  • An inverted 'T' welded to the main horizontal hinge plate with head-welded bolts to secure bracket to mast (2" O.D. !!) through two appositely designed clamps made from 10mm angle iron with two lateral flaps welded to either lateral edge.
  • Rear view of hinge plate showing the hinge-to-mast bracket and the actuator extruded to give 45 deg elevation
  • The hinge is made of a galvanized iron plate 915mm x 100mm x 10mm. It has been further treated with polyester powder paint. I have welded two 'ears' which correspond with twin stuctures on 'the fork'. These corresponding stuctures are held in place by two 16mm galvanized bolts with self-locking nuts and allowing 0.5mm play for ease of rotation.  'the fork' embraces the square aluminium boom (100mm x 100mm x 2.5mm) which is secured in place by a stainless steel bolt going through the upper and lower jaws of each fork. The bolt is missing in this demo foto, but you can still see the hole in the lower jaw.
  • The pivot points of the EchoStar 24" actuator viewed from either side.
  • The main fulcrum made up of a Kee-Klamp stopper and a thru-base to which are attached a set of professionally spliced 20mm diam. marine nylon guy ropes. 
  • Initially, I started off with 2 x 19 el Cushcraft, which I soon replaced by 2 x 4.4 lambda DJ9BV in use up to July 1997. Eventually doubled to:
  • 4 x 4.4 lambda DJ9BV - my present day array. I must mention that I am quite satisfied with the performance.
  • The four 2m EME stations on the Island.
