Thanks for your insights Matt. Yes, I will definitely be installing 90 degree elbows (heated & bent to 180) at the dish. The other end will connect via watertight fitting to router box. Another option I hadn’t considered previously is using “Southwire Ultratite Liquid-Tight” flexible conduit in a 250’ roll. Reading the specs it seems ideal for burial in these conditions . But there are 2 questions I need answered from Southwire Tech Support. One is some reviews say it comes on the roll in several pieces so has to be spliced together. The other is if that’s the case, where I can find the male/male connector - not available at Lowes, HD or Amazon. Here are some photos:
