[SFDXA] Magnetic Loops and Limited Space Antennas

/I was looking at an Article on Magnetic Loops. Actually it was about 
Limited Space Antennas but it really was about small transmitting loops.
/https://frrl.wordpress.com/2009/03/21/limited-space-antennas-the-small-transmitting-loop-antenna/
/At the bottom of the article was a large list of articles on Small 
Loops etc and I thought it might interest a number of hams that are 
antenna restricted or space challenged.//Some links may not work as this 
is a bit older.

Highly technical presentation on small antennas
All sorts of small antennas – they are better than you think – 
heuristics shows why!

The journey is the reward – An excellent adventure in loop building

Similar to my AEA IsoLoop – The MFJ 1786 Loop Antenna Theory of 
Operation <https://frrl.files.wordpress.com/2009/03/isoloop_mfj-1786.pdf>

One of the best sites I found on small transmitting loop antennas is 
http://www.aa5tb.com/loop.html
This is a PDF version of AA5TB small loop page 
<https://frrl.files.wordpress.com/2009/03/isoloop_aa5tb_site.pdf>in case 
the page goes away for some reason.

Here is a collection of links from the AA5TB page (the PDF does not have 
live links).
