I'd double check the ground and make sure it's good... Have you found the
resonant spot at UHF? Where the SWR is lowest? If it's below 440, you might be
able to cut it but I would try not to do that except as a last resort...Most
dual band antennas are already pre tuned...Chris WB5ITTÂ Sent via my Samsung

[BVARC] Mobile antenna tuning question 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. TerryTerry Leatherland, K5PGF281-455-8090Sugar Land, Tx
