I like the way it's installed. Looks good! With the addition of the spring you have made the radiating element longer, so you might have to adjust the tip to make it shorter. If you want to experiment around, try tuning the antenna without the spring and then add it after you have a usable SWR. That would be anything from 2.5:1 ratio or lower. If it gets much higher than 3:1 your reflected power "could" burn up your receiver. If you can get it in the sub 2:1 range with the spring I would be happy. Your power output is pretty low, so as long as you are not dead-keying the microphone for an hour straight you will be just fine.
Did you do a cable directly from radio to ground?

Radio should always be connected to pluss and minus. All places where panels are put together can act as a condensation, and give you noise. The antenna mount needs good ground, not just electrical ground.
Allso, did you test it with your engine running? If so, don't. The engine has a lot of noise generating places....![]()

If you turn the squelch down, you should have a lot of noise...

Have you tested reception on the radio with just a bit of wire in the coax plug on the radio? (do NOT tutch the transmit button)? Please post a pic of your radio front as the buttons are set...![]()
