For those worried about water leakage, the Times Microwave connectors ship with
adhesive lined heat shrink to go over the braid crimp; the rest of the
connector is listed as weathertight. These are nice connectors, and made for
long-term outdoor use.

Shop around for prices.
I just did a quick look on the LMR-400 cable itself, and the first 2 vendors I
checked differed in price by a factor of 3.
The only technical downside that I can see for LMR-400 as opposed to RG213 is
that if there ever is a salt water leak, the aluminum braid will fail
Funny, I started this same project literally just today. Must be the season
for mast-out work.
I also read the Internet boards where a few people talked up LMR-400.
Decide to go with Ancor RG213, because it's the same size as what I'm
replacing, and it sounds like LMR-400 is overkill for marine VH
While LMR400 is significantly lower loss than say RG8x the limiting factor in
VHF communications is still antenna height not power output. For example the
range you could expect for a typical sailboat with an antenna height of 64’.
d = 1.2246 ∗ √hf
d = 1.2246 ∗ √64
d = 1.2246 ∗ 8
d = 9.796 NM.
There are some differences in LMR400 that you need to look out for. Most
importantly, it comes in both 50 and 75 ohm impedance ratings. You need the 50
ohm version. Secondly, regular LMR400 is pretty stiff, so if you need it to
turn somewhat sharp corners (at the masthead / mast base) then yo
Pete — I did this last spring; and I’m one of the ones you’re “hearing” about
LMR-400 cable. LMR-400 has tight specs, so you’re likely seeing different
variations in connectors or manufacturers; but all the LMR-400 cable should be
identical in performance, with the exception of the highly-flexi

Kelly,
Here's how I install antennas.
