Some years ago I had some 9913, well sealed (so I thought). Gradually the swr crept up. Without a thought, it got trashed and was replaced with LMR 400. Yes the idea of syringing water out of 9913 can work, also a constant blower blowing into the 9913 can work, we can also insert small sponges into the 9913 and replace them when necessary, or we can have the 9913 running down hill the whole way so the water can drip out (makes for a wet ham shack), or we can build a roof over the 9913 to keep it out of the moisture. I could go on and on and I am sure many of you have even more creative ideas! Am I being facetious? Of course I am! Hams can be "cheap" bunch but there is place where a few extra bucks is money well spent. Anything above 70cm I use LMR600. Just having fun today!

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.
