  1. 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.

  2. Yep, be a shame to blow a 50watt radio on cheap feedline or foul antenna array. You are on the right track, take your time

  3. Ok... No argument with your interpretation. However, note the word repeater is never mentioned. Rather, they use the word transmitter. So, would that, by extension, allow any Part 90 compliant transmitter to be used in Part 95 service? Like as a base or fixed station? And, aren’t handhelds also transmitters? BTW, Inalso found this in the FCC’s response to comments on the (at the time) proposed GMRS rules changes: Several commenters are concerned that the proposal to prohibit combination radios would prevent GMRS licensees from using surplus Part 90 equipment in GMRS. See, e.g., Comments of Jerry Scott Parham at 3. This is not our intent. We will continue to certify equipment that meets the respective technical standards for Part 90 (land mobile) and Part 95 (GMRS) in both services, if requested. However, we are amending the language in new section 95.1761© to clarify the requirement in old section 95.655(a) that Part 95 GMRS radios will not be certified if they are equipped with the capabilities to operate in services that do not require equipment certification, such as the Amateur Radio Service.
