Aircom is one of several low loss lines I have used over the years in
amateur satellite operations. Others have included 9913, LMR-400,
Buryflex, etc. They all have worked fine, as long as you install the
connectors properly, avoid sharp bends which can cause the center
conductor to migrate, and do some basic waterproofing.

For instance, the original 9913 had a bad reputation of having water
run out the end. I saw it happen in a digipeater installation.
Recently, I took down some which had been in place for 20 years.
Testing with a Bird, I found that it still met specs, and not a drop
of water.


One of the more common mistakes in using 9913 is thinking you dont have to
seal the end in the shack.
Thermal pumping(heating and cooling of the coax) will draw a lot of moisture
into it from inside the shack.
