Cant tune Antenna on cascadia

While I have pretty good SWR with my K40, it's still only a 4 foot antenna. Would I get better range with a 5.5 foot Francis? I ask because the truck stop I'm at has them in stock.

 

Leave it alone, do not mess with it.you, have a decent match with a good antenna

 

Power Joints gave you good advice. But, the answer it YES, you might very well get better range. Could you tell the difference? Maybe, but probably not in normal use. You mostly likely would have to set up a test with every thing being equal and check both antennas to know what the real difference would be. I would not switch unless I was unhappy with what I had.
