Record your SWR numbers on ch1 and ch40. Loosen and adjust the antenna 1/4" down into the mount and record you numbers again. Keep doing this until you get the lowest numbers on your SWR meter. If it has been dropping and you bottom out the antenna mast in the mount then it is time to start trimming it. You have about an inch of adjustment room.

This is how I'd tuned it originally- I think I was somewhere around 1.5 on both 1 and 40.
Now I'm trying to figure out what's changed and causing it to be so high.
Anything 1-1.5 is golden. The soldering where the coax is attached to the antenna is minimal. It is a high fail point. 
If that is where the problem is it is a good idea to shorten your coax to eliminate any extra wire. This will increase your gain. When you resolder (if that is the problem) you will need to re-run your SWR antenna tuning as that affects the resistance as well. Shortening the cable does the same but decreases some line loss.
