Best bang for the buck* on coax for a VHF or UHF base station is Times Microwave LMR-400. ...just don't use it for a repeater. (reasons discussed elsewhere on this site) Also, watch out for fake Chinese LMR-400 "Type" coax, as some of it is sub-standard, or just re-badged RG-8u. If it isn't from Times Microwave, then it isn't true LMR cable, which is a registered trademark. For repeater use, you really need to use Commscope AVA5-50 or larger, depending on length. (NOTE: This is the new part number for what we all call 7/8" Heliax, also a trademark.) If you want to go cheap, and still get good results, check out the less costly RFS Cellflex LCF78-50JA. This is a 7/8" line very similar to "Heliax", but not... kind of like grocery store facial tissues are very similar to "Kleenex", but not. *NOTE: The above is my personal professional opinion. The views and opinions of others may vary.
