Yup, there's even a video of THIS! Amazing, soon we'll see people opening up utility bills on youtube. Anyway, if you've always used RG-8 or RG-213, this is a nice step right past LMR-400 and into the real stuff. This is the last step before Heliax. The difference w/ 600 Vs the first 2 mentioned is just way too undeniable on VHF and UHF.
