Once again for the benefit of any new hams who may be reading this 9913F is a modern version of the old 9913 air dielectric coax, Like LMR400 it's now a foam dielectric coax which is easily identified by it's tinned braid and bonded foil shield. 9913F is no more and no less susceptible to water intrusion/migration than competing products.

“The Bottom Line”: 9913F7 has almost exactly the same physical and electrical assets (size, flexibility, low attenuation) of LMR-400UF, with the added advantage of lower replacement cost due to longer life.

Actual Impedance specification is 51.5 +/- 2 ohms. Max. Pull Tension:

I feed it with 7/8" CATV hardline and above the rotor, I went with 9913F. Yes, this coax is MUCH better. Multiple strand center conductor, foam dielectric, etc. The original 9913 was a great concept, but it had it's limitations. Time Owned: more than 12 months.
