Heh, somebody didn't do his homework. In a word, compare.

Just maybe if you look at the spec sheets for their other products you may draw the same conclusion I did, they're marketing Times Microwave.
You are correct, I did not check the specs for the other cables. In fact at first I thought it WAS TM's LMR-400 cable, but when I viewed the product I saw this at the beginning of the description: "
JEFA Tech Low Loss 400 is a high performance
alternative to CommScope® WBC-400,
Times Microwave Systems® LMR-400, Belden® 9914 / 9913 / 7810 and Andrew® CNT-400 coax cable." (emphasis added) I did compare it to LMR-400 which shows slightly less loss than LMR-400 at a few freqs and a significantly lower cost per foot. Which is why I asked if the quality was on par with the Times product. If they are marketing TM LMR-400 under their label, I think that's what your point was, they are doing it at a great price. And that would answer the quality question.
