Tom and all,
My apologies for ignoring the list for a time.
That spool is a bit more than I need (even ignoring the distance
involved), but your message does make me think that obtaining some
thicknet is going to be a challenge. It is not exactly conducive to
shipment by parcel post. What is the minimum diameter that thicknet
could be looped and still be straightened back out? I suspect that, like
electrical conduit, it is "bend twice only" and pulling it off the spool
counts as the first bend.
At some point I may try to have some shipped directly to InfoAge for the
MARCH museum but I need to make it work at home first.

I have a spool of thicknet here. It's marked "DEC" and of course has a
paint mark every meter where you can tap it. There's an N-connector on
one end, the other end is cut.
The spool is marked "320 feet" but I don't see how there can be that
much on it. I believe there's two layers of cable left wound on the
spool, 42 turns, 57" from one point on the spool to the same point on
the next turn (very approximately) yields, whoa, 399 feet? Hmmm. Well,
maybe there is 320 feet on it.
I had thought to use it for amateur radio, since it's the right
impedance, but I dunnol how much loss I'd see at VHF frequencies. I use
50 and 144 MHz radios, and 440 MHz UHF but I don't think this stuff is
any good for UHF. But my problems would be terminating it in anything
but an N-connector, and the fact that it would break down rapidly from
UV exposure if I try to use it outdoors.
Make offer. Pick up in Southeastern Wisconsin. Or call a motor freight
company for a quote for pickup and shipping from 53051.
