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
