Milt, Mike, and all:
I use 4-hole chassis mount F connectors because like you said, the single
nut F connectors loosen up after awhile with temperature changes. Mouser
carries them but I got mine from Surplus Sales of Nebraska for 30 cents
each in 100 quantity. These also have an o-ring on the flange which makes
them very water resistant if not water proof.
I use #4 stainless steel screws with stainless steel Nylox nuts from Mc
Master-Carr and no problems so far.
Hardy, N7RT
