The antenna is a 1.4 prime focus dish from www.satellitesuperstore.com . Technical information: The ratio of focal length to aperture size (F/D Ratio) is 0.41, Gain at 10.95GHz 41.8dB.
As you see, the stand is kept in place with ~ 280kg of lintel, breeze block and slab.
The dish was aligned using the sun on March 1st, 2019 because at 10:16 the sun's azimuth and elevation was the same as Es'Hail 2, so the shadow of the feed would be directly over the center of the dish.
The current options are:
- LimeSDR (USB) and
The LimeSDR was chosen because it supports an external reference (I use the Leo Bodnar unit) so is more stable.
Testing with an Octagon 0.1db Quad High Gain HD Ready Universal LNB. This is very sensitive but drifts - for SSB / CW it must be modifed, either change the crystal to a TCXO or add support for an external reference. Drift is much worse in the daylight for obvious reasons.
