For any runs on HF over 100' I use LMR-400 the same for any length run for UHF/VHF coax is cheap in the long run you get what you pay for. It can be reused in the future if plans change. Always be on the lookout for CATV cable spool ends whatever usually it's free and good stuff for your use and can be buried to boot.
