This is my lightly edited dialog with Microsoft Copilot. Initially, I ran "Deep Research" against the first prompt.
I want to create an electrical schematic for a broad band (10m - 20m) balanced amateur radio antenna with a balanced feed line that is connected to the transceiver at via a Z-match antenna tuner unit (ATU).
- There will be two 50 foot long LMR 240 coax cables whose cores ("C+" and "C-") will feed two the two antenna radiators ("R+" and "R-", each 29 ft long and horizontal, oriented anti-parallel to one another, fed at the "proximal" end with no connection at the "distal" end).
- Label the ends of coax as "T" for transciever and "A" for antenna.
