I read somewhere that the absorbant material had an impedance of 377 ohm per
square. J Kraus showed that space cloth of this impedance reflects 30
percent of the incident wave.
Is space cloth still manufactured? A google search turned up zero hits.

Tnx es 73, Frank


I last purchased 'space cloth' [122 ohm/square] in 1990. I don't know if
it's still manufactured.
