As a philosophical thing, I tend to prefer installation schemes where 
there's no annual/periodic maintenance required.

That's one of the advantages of, for instance, exothermic welding 
(Cad-Weld One-shots) over a compression clamp.  Or of crimp fittings 
over bolt on.

I know others have different opinions.. some enjoy the annual 
inspection.. maybe it's like signaling the change of seasons.

And I will readily admit that there are other things one should do with 
one's antenna system on a periodic basis (e.g. checking the cables, 
etc.) so maybe it's just a matter of having a checklist and adding some 
stuff to it.
