Antenna redo.

Made an antenna guessing at the specs. Also did it do see how critical the angle of the dipoles were. Antenna pattern: http://web.archive.org/web/20130610164242/http://tradewhen.com/Log-Periodic-Pattern.pdf

Original version:


The antenna did not work that well. So I went back and looked at the original picture and noticed the angle was quite different.






Oops, the original angle used was a bit wide. Hmm. S/B:

Now, the new version with the corrected angle.


Now to test it. Tested average....

You actually can do a minimal windowing from the command line in Linux with dvtm. Dvtm is excellent for low end machines where graphics are not a priority.

I prefer vim, but nano has more of a user interface. Cheatsheet: `dvtm` is one simple, easy-to-use terminal multiplexer.

KeyBoard Shortcuts:     Mod    Each keybinding begins with Mod which defaults to ^g but can  be               changed in config.h or with the -m command line option.                       Mod-c  Create a new shell window.            Mod-x  Cl
