What’s your integration time again? And is this the Milky Way? Have you been able to observe anything beyond the Milky Way with the dish?Īlso, is 1.2m the long or the short diameter of the dish? Since it’s an offset, the short diameter is the one that should concern you and should be used to calculate antenna Beamwidth etc. I had to use elbow connectors at the back so the LNA was away from the dish arms in order to adjust, whatever works.Ī plastic tube hot glued is then the connection to the LNB holder long enough to adjust focus (which I need to do yet!) Would recommend using a copper reflector, I only had a piece of sheet steel and had to use a bit of copper circuit board to join the n connector to the element and screw together. I used 1.5mm electrical solid core to make the diamonds. source=web&rct=j&url= ved=2ahUKEwiNxNab8K3dAhWMLsAKHQVYB0cQFjABegQIBRAB&usg=AOvVaw1JCwSFCn-kzwmHTIRK8xWT Use the second calculator the first is for a four-way. The feed is a biquad normally used for WiFi long range and works well with dishes. Yes to get the Yagi working I added a a reflector tin biscuit lid which helped big time and eliminated some ground noise. I would be interested in the details of the feed design I guess the dish will have a better front/back ratio too which should improve SNR.
