1296 MHZ EME

Under Construction

  1296 EME Station:

  The dish is fitted with a W2IMU* feedhorn, G4DDK VLNA, and 600w solid-state power amplifier.
  This permits running less expensive LMR-600 hardline to the dish.  First 1296 MHz EME operation 
  on the 4.9m dish was using a 60w amplifier in February  2014.
 
  *Previous feed was a septum; Go here for information about the Septum Feed.
 

 
 
 
 
 
 
  
  October 2, 2020:

  Removed the dish using a boom truck, today.  Hoping to have new base tower and back structure completed and dish
  re-installed by end of the month.  Will add some photos of the progress.

  Dish on the ground

  July, 2020 Update:

  Purchased a model SD-12 Sun-Slew helical drive for my dish (July 2) and should arrive from China in two weeks.  
  Sun-Slew Description

  Here is a prelimnary redesign for the dish mount:


    




















  January, 2020 Update:

  Significant damage was sustained to angle-steel back-frame of the dish when the 1/2-inch bolt holding the elevation
  actuator sheared while we were on extended vacation in summer 2018.  The dish dropped about two foot with a slight
  deformation on the lower edge.  Repair will require removal of the dish, so this presents an opportunity to redesign
  the azimuth drive using a helical screw drive and redesign the mount to a pedestal type.  This planned for summer 2020.
  Quad feed support will be replace with a more substantial one.  1296 and 3400 MHz is QRT during this period.
 
  April, 2018 Update:

  New W6PQL 600w amplifier has been purchased which will replace the 300w amplifier.

  Details of the original dish are now archived since redesign is in progress
