Yes. The coax is primarily aluminum jacketed CATV hardline.  John used
a lot of that.  Roughly 1/2" dia rather than 3/4" it looked like to me.

I was able to save quite a bit of John's AMSAT history this morning
which I am very happy about.  It was a huge part of his radio hobby and
his life so this is good news.  I will be sorting through it for a while
but hope to send out some photos and little stories about the stuff as
time permits.

One example is a development system for the Phase-III IHU computer
that ultimately flew on AO-10.  This is a two board set that is the
same design as the actual flight computer but instead built from
non-radiation hardened CMOS and was used by the software development
team to develop the flight software.  This computer is based on the RCA
1802 microprocessor that some may remember from the COSMAC ELF c. 1976.
Because it was CMOS, it was very low power and flew in a number of NASA
space programs as well as other AMSAT birds.
