[QUOTE="IanW, post: 646220, member: 176464"] Hey Yasha, I would keep it simple and separate. 2 antennas. 40E - C-Band only. A small (90cm) prime focus mesh (perforated metal reflector) with C-Band circular polarised feed. You can use a conventional linear C-Band LNB and prime-focus linear C-Band feedhorn, then add a Circular > Linear de-polarising teflon slab inserted into the feed throat. 36E - An 60cm / 80cm offset Ku-band with Ku-band universal LNB. And a DiSEqC switch at the antennas. The 90m cable is not a problem, but you will need an 'in-line' L-Band (950MHz - 2100MHz) IF amplifier, ideally placed 45m down the co-axial cable, that is halfway. You might like to test ALL the equipment on the ground, including the 90m of cable before going on the roof :) Perhaps you can install the antennas so they are protected from the wind ? Good luck, IanW. [/QUOTE]
