Title: Ethernet cable Post by: wavebourn on February 08, 2005, 07:48:25 PM Hi!
Is 10-base-5 cable (802.3) usable for antennae feeding? (http://wavebourn.com/images/10base5.jpg) Title: Ethernet cable Post by: Barry on February 08, 2005, 10:07:55 PM I think that is called 10base5 it is like a quad shielded RG8.
It has 50 ohm characteristic impedance and I have used it to make coax jumpers between various pieces of equipment. The only problem with it is that it is very stiff and heavy. (not flexible ;-) You would need some real support to feed any type of wire antenna that was off the ground with it.

So, your opinion is that it is better than usual RG, electrically? Title: Ethernet cable Post by: W2VW on February 08, 2005, 11:07:20 PM The stuff I have here is Belden 9880 Ethernet Coax. It might hold up a little better under high SWR conditions and the shield is certainly better than most RG-8.
