Not much info out there on these Sinclair products. However I did find a barely readable label... the antenna I have is an SRL210C4.
I found this: http://forum.radioamateur.ca/index.php?topic=2245.0 which is helpful. (Google Chrome translated it fairly well, except for the last post by VE2TBU. Given the limitations on translation, I'm not quite sure what he said. :-) I'm working on disassembling the old beast now. Naturally there are a few stuck set screws..... I will share whatever I learn during this project. Unfortunately my digital camera died so I won't be able to take pictures. Paul N1BUG wrote: > Me again.
