I did notice that there was a couple Allen set screws holding the whip portion to the base coil unit of the antenna. I loosened the screws and was able to pull the whip out a bit further. By doing so, I was able to bring the sweet spot down a couple of MHz. Not a dramatic difference, but some none the less. I'm starting to think the best idea would be to start off with a 2-meter amateur antenna and cut it down until covers the spot I use the most; easier than adding length. True, my antenna seems to work fine now regardless, but I'm just playing with it because I can.

Hi Ron,
So (you probably know this) if you want to lower the resonant freq of your
antenna you need to make it longer.
There may be an inch or so of adjustment if you loosen the set screw at the
base of the antenna.
Although I might add that you have swr of 1.5 at 155 which is still quite
good. And if you are rx only you likely would not notice any gain or
improvement at all.
