True, because bending the cable alters the geometry and introduces

Thinwire (10base2) and 10base5 are electrically very similar. There
is a difference (I forget what, but I seem to remember if you used the
common 8392 transceiver IC there is a

He said he has connected a 47 Ohm resistor at each end of the
coax. That's close enough to the correct 50Ohm terminal to
work.

You will need to terminate the coax.

Typical installations would use "N" connectors.

The cable segments on each end should be (at least about 3 feet) before the

Tuesday night, I got a small 2 node thicknet segment going between my DEC
