Richard:
don[t know much about the 480. However, you probably mean sgc tuners.
generally good, but quality can be variable. I don't recall which of them are weather sealed for outside mounting.
My recommendation is a good manual tuner in the shack, or get an mfj 993b auto tuner. With some judicious labeling, they are perfectly accessible. also have a very wide matching range.
I used one for a while, but sold it because I didn't need it.
