In order to do proper cabling for 10 GHz transverter for positive and ground cables I have some questions. For positive power a sequencer is usufull to protect coaxial relay from hot switched and PA from SWR during switching (in my case there is no problem as a circulator exists). For ground cabling is more complicated. There are three ground paths. One is the RF path via the semirigids between shielded boxes. The other one is the metal box that the elements are fixed. And finally the power path that provides power. The question is how to properly cabling it. The current of the PA is about 5 A. Any proposals are welcome !!!
