Which Coax Did I Want Again?

How many ways is this question asked and answered? There are a gazillion articles on the topic. I have been reading. A lot. And here is what I have come to find…

Most of my coax has been RG8X, across the board. I didn’t really know much better, it is exceptionally cheap, and as far as I can tell, my signal is leaving my radio and exiting out through the antenna. So what have I learned…

For the average home amateur radio operator there are more options than just RG8x and LMR400. I know! Blasphemy! Like 90% of the conversations revolve around those 2, unless you are doing repeater work with the club and someone mentions Heliax or hardline. Well guess what. You should add a couple more.

RG-213 – Sort of the little brother of LMR-400 for HF. About 1/3 less loss than RG8X. But… if you are even remotely thinking about any kind of amplifier in the future, then RG-213 may be the cable you are looking for. Where RG8X is only good for around 400 watts in the HF bands, RG-213 can handle over 1,200 watts, easily. Is not as large and bulky as LMR-400, but is certainly larger than RG8X.

LMR-240 – Never heard of this before? If you are running portable, or insist on running RG8X, then you should also be considering LMR-240 and LMR240-UF. The “UF” is for ultra-flexible. With a 35% or better loss advantage over RG8X, in nearly the same diameter and flexibility, with almost 3 times the power handling, LMR-240 is a drop in, high quality replacement to RG8X. LMR-240 is also sort of in a sweet spot where for shorter runs, it also works well enough for UHF/VHF. For your Go-Kit cables, or field day setup, LMR-240 is a great option. I just used ABR Industries to order several LMR-240 cables and can’t wait to try them out. I will do a review in the near future.
