    monopulse comparator or te21 mode couplers?

    Dear All, We will track a LEO satellite with a large reflector (program track is not enough).We have foundmonopulse comparatorte21 mode couplersWe are not sure which one to use to track a satellite at 8 Ghz? Can anybody help?

    Large Parabolic Panel Reflectors for 10 Ghz EME

    Dear All, We will try to construct a Cassegrain Antenna for 10 Ghz EME. We need to construct a large (at least 5 mt.) Parabolic Dish. We don't want to buy a one piece reflector, we want to buy panel reflectors to build it. Unfortunately we are having trouble finding a supplier for Large...

    dichroic subreflector

    Yes we are reflecting the X Band and the Subreflector has to be transparent to the S Band. The other Specs are: RHCP polarization for X-Band receiver (8.025-8.375 GHz) LHCP polarization for S-Band receiver. (2.2-2.3 GHz) RHCP polarization for S-Band transmitter (2.04-2.12 GHz) Also there is a...

    dichroic subreflector

    We would like to build a dichroic subreflector which will be used in a S+X Band Parabolic Antenna. Dichroic surfaces are transparent to one frequency and reflect another. In our case the frequencies are in the S and X bands. How difficult is to design and build such a dichroic subreflector?
