[Elecraft] Antenna and Propagation class notes addendum

[kevinr]

I spent last night waiting for the power to go out reading these lecture 
notes.  I found part of the file was missing.  Upon further digging I 
found the original site where the entire class is located.  My rusty 
German helped me find it.  Luckily it is technical German where the 
words are one line long :)  That gave me a foot in the door allowing me 
to translate a few parts of the compound word.

That led me to : ihe.kit.edu/mitarbeiter_859.php

The noise segment has more math than does the rest.  Luckily, the 
propagation section has very little math and a lot of substance. I found 
this lecturer's pace and order very good, much better than the text we 
used in my second antenna class.

Do not let the math intimidate you.  Read the text around it and you 
will gain a lot of information without needing to work all the 
problems.  I found a few Bessel functions which still give me pause.  
These notes are from a class about two years ago so it covers cell phone 
antennas, both in the hand held unit and in the towers which repeat the 
signal.  The section on beam forming methods was interesting too.

Good luck, learn much, and 73,  Kevin.  KD5ONS
