Specifically, that's a brand of coaxial cable. Times Microwave is the name of the company and "LMR-400" is the rating of cable. Welcome to Times Microwave
LMR-400 is of higher quality and generally used at the higher frequencies (UHF or above) when signal quality is important. The cost is higher but still very affordable even at longer lengths.
Like with anything however, the brand name can determine cost. Generic LMR-400 can be quite a bit cheaper but it's possible that its quality control isn't quite the same.
