Topband: Mobile swr

[olmsted kevin]

New to topband reflector.  I have been running mobile 160 with vswr swinging 
up to 2.0 to 1 depending where I may be, nothing drastic like tractor 
trailer etc..  I have bonded all soldered conections.  The unun gives me a 
perfect match whith my Hi-Q 5-160.  The other nite I saw corona off the tip 
of the whip would this cause vswr?  Any sugestions on how to tame vswr while 
driving. The 2.0 to 1 kicks my als 500 m.  Thanks for any help.
