 I just put up an inverted V for 30 meters. 
 I started out with each leg being 24'0". This 
 gave me a low SWR at 9.5665 mhz which 
 works out to 229.6 instead of the usual 234/F. 
 
 As I trimmed, I decided to keep track of how 
 much I trimmed and what the nnn/F number 
 would be. As I got closer to my goal of 10.15, 
 the number went down, eventually ending up 
 at 227.28/10.1955=22.292' Also, the 2:1 swr 
 bandwidth went up - it started at 567 kc and 
 ended up at 655 kc. 
 
 Either way, I got the antenna up and it's working 
 fine - I'm just curious why the formula for length 
 and the bandwidth changed as the antenna got 
 shorter.

234/f is just a starting point.
