Picking up on a comment in a previous thread on coax traps

....

I have put some notes together on a draft page proposing a
mathematical model for these traps.

The draft is at http://www.vk1od.net/coaxtrap/index.htm .

This is a different approach to any that I have seen, principally
because it treats the coax section as a transmission line (as I
believe it is). That is not to say it is correct, so if anyone can
identify errors in the document, I welcome their feedback.

I have not constructed and measured the example trap. Construction is
easy, I just don't have equipment to perform high accuracy
measurements of RF complex impedances up to around 100k.

Comments appreciated.
