Jerry, top effort mate!

I am looking into it. So much to do, so little time. I am quite excited about all this new stuff I am gaining knowledge and interest in

. I had a bit of a listen on my receiver today, hooked up to the new antenna. I tuned in a few frequencies between 18 and 21.9 mHz. Dunno what Im listening for but I reckon if I keep doing it, I will start to recognise certain sounds very quickly.
I would love to see a bit more on the plans you posted there. I don't understand too much of it yet, but enough to get your drift. Pictures say a thousand words and all that.

Whats a balun? Why 300ohm lead? Is that the coax cable from antenna to radio? I am using 50 ohm at present.I have wire, poles of all descriptions, conduit, and can get my hands on coax and fittings readily. And all the tools I'll ever need. Ready to start building antennas!
Again, thanks Jerry and top effort. This site is a brilliant forum for us nerds as everyone is helpful and forthcoming!
Baz.
