NN7J asked: >What is the F/d of dish network dish? .69 F/D is what I calculated it >out to be. Also looking for feed design for 5.7 GHz.. 10 GHZ. Unless it's a unique reflector for Echostar, I believe bog standard Ku-band LNBFs for offset reflectors are designed for an f/D of around 0.59 & an edge illumination of around 12 dB down at 39 degrees. 73, VR2BrettGraham |
