[TowerTalk] Fwd: Fwd: hardline bending radius

[Hans Hammarquist]

Hi Jim,


No, I don't have a part number. I purchased a roll (of 442 feet) at an antique auction for $1. Nobody know what it was. As it couldn't be used as a water pipe most people found it useless. :-) The jacket is solid black without any marking. I measured the loss of 1.2dB @ 65Mhz for the 442 feet length I have. (I am not sure about this measurement as the cable Z=75 ohms but the analyzer is for Z=50 ohms.)


The outside diameter of the aluminum shield is (pretty much) exactly 1/2 inch. The dielectric is foam. The center conductor fits very nicely inside the center pine of a PL-259. I seen the same cable used by cable TV companies as trunk cable.


I will build a bending fixture myself. That's the reason I want to know the minimum bending radius. I don't want to build something just to find out it was wrong and have to build something else later.


73 de,


Hans - N2JFS

Have you got a part # to look up the mfr data sheet?

Have you got a bending jig or tool to support it so it doesn't kink?
