Less than 1/2 the loss of RG-214 but yet the same diameter:

Made for outdoor use. Better shielding (solid in addition to braid) more
flexible, better UV protection, 20 year life expectancy. Much better
performance over its lifetime. When it finally does degrade to near the
dismal performance of RG-214, then replace it. It's even cheaper than most
places charge for RG-214 at retail.
