I am a late bloomer in ham radio.  I was not an engineer in a former 
life, and am still grappling with basics.
I still find matters of  IMPEDANCE ...SWR... reactance... radiation 
resistance, etc., a puzzlement and a curiosity.    Taking college 
physics 35 years ago is not making it for me...
I am still "corn-fused" about the relationships between these concepts. 
  For example,  my 43 foot stick had these different results before and 
after I converted it to a 33 foot 40 meter ground plane.
______________________________________________________
SWR  @ 7.150 MHz  @ 43 feet =   6.8 : 1     |Z|= 55 ohms
______________________________________________________
SWR @ 7.150 MHz  @ 32 feet =   1.40 : 1     |Z|= 38 ohms
______________________________________________________
So... at 43 feet, I suppose I get a great impedance "match" at 55 ohms, 
but at the expense of relatively high SWR...    So I shorten it and get 
a great SWR "match"   at 1.40 : 1 SWR, but at the "expense"  of dropping 
impedance to 38 ohms  (which is pretty much according to the text book.)
Do you guys know of a chapter in the ARRL Handbook or the ARRL ANTENNA 
BOOK, or some other place where I can read up on how all these concepts 
relate?   Personally, I find it all very corn-fusing.
I am not complaining ...  no mamby pamby whining going on in my shack... 
   ;-)
I am just trying to understand what it all means !     So if you could 
point me in the right direction, I will do my homework.
