[QUOTE="deeptho, post: 1136677, member: 215446"] I guess these things are not as standardised as other LNBs. By the way, I found a chinese Ka-band lnb here: _[URL]https://www.aliexpress.com/i/1005002629719890.html?gatewayAdapt=glo2fra[/URL] L.O frequency:18.25GHz Satellite:19.2ºE,42ºE 19.2E has muxes in the range 18.5-18.8 Ghz which should be band A, but the LO according to your list would be fore band B. 42.E has muxes between 18.7 and 18.8. With an LO of 18.25Ggz the RF output for 18.5-18.8 should be in the range 250Mhz - 750Ghz, which does not make sense. So something seems wrong. Maybe the oscillator is 17.5 GHz? And indeed: the picture (after magnification and rotation) says input: 18.2-19.2Ghz Output: 950 - 1950 Ghz Gain: 50 dB noise. 0.7dB Would it be useful in Europe to invest in such band A LNB, given that it is still quite expensive?
