2,5 m offset dish -

 

Installing dish in the garden - 08/2019

After removing of 10m mesh dish, I am building first MW part of my new project. Following pictures showing progress with ground work and mechanical part of AZ and EL system for 2,5m offset dish. This system will be use on 10 and 24 GHz mainly.

 

 
 

Build and testing mechanical parts before installation - 2018

I have available 2,5m offset dish made by Prodelin USA, which I am expecting use for EME on 3 & 1,2cm bands. From beginning I had available just dish and back frame for dish fix mount. Choice of MW bands is requiring very high accuracy of dish position during pointing to the Moon. I have build small mast, azimuth frame and elevation bearings. All accuracy is focusing mainly for 24 GHz operation use. On following pictures you can see the mechanical part of dish rotating and elevation.

 

Main mast for dish, snail gear will be on the top
