A solution for the home station is to use waveguide for the feedline. One of the first problems that you encounter is the loop around the rotor. One method might be to use waveguide to coax transitions and a piece of coaxial cable for the trip around the rotor. It would work in some limited fashion, but if you are going to the expense and time to install waveguide then you might as well go the extra mile and use waveguide all the way. Fear not there is a way.
Flexible waveguide is a viable method of bridging the rotor.
Once that problem is solved the rest of the installation is relatively easy. The method described here has been in use at my 10 GHz home station for over a year now with no degradation in performance. Total feedline loss from the shack to the dish is very close to 3.0 dB. Not great if it were 432 MHz, but certainly not too shabby for a home station on 10 GHz. The total run is about 50 feet to the top of the tower and another 15 feet to the dish. I use elliptic guide to the top of the tower and then the setup shown in the drawing above.
