Hi all. I am about to order about 110 feet of coax for a new MA770MDP tower/ Steppir DB18 install. I'm thinking of using either genuine LMR400 Ultraflex or Davis Bury Flex coax.

Davis BuryFlex is cheaper and I understand it has a tougher and more slippery jacket for crank up/down use? Opinions?

I am going to try crimp-on RFU-507SI RF Industries PL-259's for the first time. For the center conductor crimp, I have alternatively heard of .118 and .128 crimpers being used. I have the dies for both .118 and .128 as well as the .429 braid crimp. Any opinions? Do you use any dielectric compound such as STUF inside the PL259 to inhibit corrosion?

Tnx, Howard W6HDG
