Double/Dual commercial feed horns for 10GHz and 2.4 GHz

    Dear all ,


    I would like to know IF there are commercial antennas/dual feed/double for QO-100 , ( in essence what the commercial ground stations use to communicate / monitor the space craft )


    I tried to find something but my search got complicated fast , and I am in need of some help with this subject.

    My reason of asking this is as time goes on more radios come into play for 10GHz and you guessed it I am talking about the new ICOM IC-905 that has a 10GHz up/down converter. ( how broad the 10GHz will be or if the radio will be dublex thats is a whole other story. )

    But I would also want to go down the rabbit hole to also eliminate any need for downconverters and external references to make the most rock solid setup. Since everything will be native to each other I will only have a need for a single radio with a single reference. ( aka if it will work as expected with a good GPSDO the ICOM IC-905 and Lime SDR LMS8001 Companion

    I hope you can help me in my endeavour for knowledge and fun ,

    Thank you in advance

    P.S.: If this question has being answered already I am sorry in advance for asking again.

    There are commercial 10GHz antennas, but I am aware of nothing that has been combined with 2.4GHz. At this point, I would recommend waiting until we know the exact frequencies available with the IC-905. There are enough brilliant people out there that will be excited and ready to make a combination antenna for use with QO-100 once we know more about the IC-905. Until then, save your money (a lot) for the IC-905 :) Remember, the amateur radio frequencies available are 10.0 to 10.5GHz and the NB transponder is at 10489.5 to 1049.0. Let's just hope Icom will make the full amateur radio band available. Should be common sense. :)

    Dear Stefan ,


    Yes I am aware that I am looking too far ahead to the future ,


    BUT , having intricate knowledge and ability to decide what antena would be able to be used best in this setup regardless of transmitter its a plus.

    Regardless the ICOM is safe to assume that uses an down-up-converter because it plus in the 144/430 port and also get the 10mhz ref out from the main box ... so its safe to assume / say that its just a 144/430 down-up-converter from 10ghz or other freq. ( i saw that you can swap other antenas besides the 10GHz ones. )

    But again in general in case something drops off a truck ( ;) ) that can go up to 10GHz it could be fun to experiment natively on that band.

    nevertheless Thank you very much for taking the time to answer my question :D

    Regarding antena building , I prefer to use as much as commercial / ready made parts. To have a robust system/ be able to get the ability to move forward with other SATs in the future

    Thanks again :D
