5 Meter Dish Antenna for Geostationary Satellite Reception

This 5 meter C and Ku band prime focus feed antenna is in my back yard. It is sitting at 35 degrees elevation but at 5 degrees elevation it stands 35 feet tall and created numerous complaints to the city after I erected it. After a lengthy battle with the city Nazis, it is now legal!

The antenna itself is a Prodelin 5 meter cassagrainian feed paraboloid. The Love horn feed was strictly C-Band and I wanted Ku as will. The dish surface isn't sufficient to not blur Ku band so to improve the situation, I modified it to prime focus and dual band.

Everything imaginable is relayed via satellite, so it is just a question of receiving and demodulating what the satellites are already broadcasting into my backyard. Some of the digital modulation formats are too difficult for an amateur; requiring any one of: QPSK, QAM OFDM, and DQPSK demodulation, followed by descrambling, FEC detection and extraction, deinterleaving, Veterbi and Huffman decoding. At data rates much above T1, I'm out of business because of the real-time complexity issues. Also one can spend a lot of time working a signal, only to find out that it doesn't yield to reason anyway.
