Hello David,
 
In addition to SWR bandwidth, you will also encounter another  issue that U 
will need to resolve, and that's angle of radiation.   If  you are 
interested in talking to guys relatively locally (zero to a few hundred  miles), a 
horizontally strung antenna (a dipole or inverted V) will work much  better, 
as the vertical you have has a relatively low angle of radiation, and DX  
stations will be favored over the locals (unless the station U are working is  
VERY close by).   Another consideration for this vertical antenna is  
grounding.   Verticals work MUCH better if a suitable ground is used;  at least a 
few radials a quarter wavelength in length (about 60-65 feet) should  be 
strung out from the base of your vertical, if decent performance is  wanted.   
Good luck and 73,
 
Herman, N4CH.
