[QUOTE="Channel Hopper, post: 599811, member: 175144"] Without a picture of the rear structure, it could be one of about ten designs. Is it a receive only, or receive transmit dish ? Does it have actuators to move it ? What are the maximum / minimum temperatures over a year in the area ? Prodelin uses SMC compound, (not quite fibreglass) that is heated in a press with the metal mesh to form the reflector panels. After a few years in the field, the three main issues that can affect the dish are 1)Delamination of the mesh away from the backing compound 2)Brittleness of the reflector edges (taking it apart without causing fin/hole enlargement is going to be your main priority) 3) Distortion of the reflector due to weight and temperature changes. A picture would be very handy, and any idea on whats bolted to the focal point. [/QUOTE]
