[Elecraft] Urban stealth HF: Inside-the-backpack loop antenna?

[Paul Wilton]

10+ years ago, we built a HF loop inside a coat.  I can’t really tell you the application but the loop was made of copper braid and put between the liner and the outer shell of the coat.  It was tuned with a simple L match with a LED to indicate peak power.  We operated it on the 80, 60 and 40m bands.  The drive was an FT817 at 5w.

We weren’t trying for DX but it worked well for the short distances we needed it to work.  It was also pretty easy to tune up and and once tuned stayed there.
