Anyone on the list aware of machined blocks to support the Russian EHF SRD multipliers on the EPay or EU region?
Second question: I have a weak signal source - a LNB diode soldered across an SMA bulkhead connector. There is a small DC return/choke with a tiny wire loop from the center pin to the ground. Works great.
Would this method apply to a vivaldi pc board antenna where the diode is essentially across the feed hardline and the metal surface provides the dc return?
