Yes, but wet 9913 has a loss of ?

While searching for some hardline to replace my 9913 run some years ago,
I resorted to drilling a hole in the bottom end of the cable, and
sucking out the water periodically with a syringe.  It was not an
insignificant amount, and made a huge difference.  Eventually found
someone with some leftover LDF4-50A hardline, and made a swap with him
for a UHF beam antenna I had extra.  Best deal on the planet.

If you can truly keep your 9913 dry inside, by all means, go for it. 
But how do you know it's still dry?  To me, it's not worth the trouble. 
If you like that size cable, I'd go with LMR-400 instead of either
variety of 9913.
