Bases have gotten bigger. Crankup mounting plates have much heavier steel and angles rather than plates. The catalogs show much less concrete than the actual wet stamped drawings I have for my HDX589

Tough question, but I'll try to answer. It's hard to find deals on 50-ohm hardline. I assume that's what you're looking for. Brand-new LDF5-50 is $5.75 per foot from The RF Connection. I assume that'
