I'm sure someone knows about Mobile antennas. Our friends at River Oaks Car 
Stereo for sure. Anthony?
Here is my dilemma , or something I am doing wrong.

I bought this antenna to mount on my new truck. I have a brand new Comet 
analyzer. The antenna is hood lip mounted with a comet Hood mount.
When I analyze the raw antenna thru its one piece of coax, it is perfect 1.5 or 
less on 2Meters @ 50ohms.
But when I dial up  to 440 Mhz, the swr and Ohms is off the chart.
My radio is my old reliable Kenwood TMV71 of which I have 3 identical.

Shouldn't I be able to just change the band knob to 430 and it read good SWR?  
Do I have to find the resonant point of the upper band and start trimming the 
top length down to 440 good swr?
I'm perplexed or doing something dumb.

Terry
