180cm DISH - portable 10 GHz setup

Manual of 180cm prime focus dish

Used for SAT RXing

Dish arrive well packed and in good conditions

 

After the test of my existing 3,2 m portable mesh dish I decide to use something with better aperture for my EME peditions. On the E-Buy I have found dish presented on pictures in left side. Thanks to Peter G3LTF I have dish at home, because company in UK does not send the dish direct to Czech republic. For my EME application was necessary to made some upgrades and mechanical changes as follows. I have completely changed also screws, bolts and nuts.
