It is poorly suited for feeding end feed antennas. It is a balanced feed line so it works best for feeding balanced center feed antennas. General things I have found from real world use. (24awg) If you try to run 100W 2M FM into it, the first 20 or so feet of line will get very hot very quickly.Īpproximate attenuation for normal off the shelf cable.īelow 15Mhz is the roll off point where losses drop to basic IR2 levels. I have generally found that a single pair can comfortably handle about 100W SSB from 14Mhz on down. So it works good as a set of four matched transmission lines in one jacket. It is a result of the stringent timing requirements of 100Mbps+ Ethernet. The velocity of the 4 pairs are pretty much the same. That means it is useable for longer runs 14mhz and down, while only usable for short runs at 14Mhz on up. It has an attenuation curve a little bit higher than run of the mill rg58. I have found that it works pretty good as long as you take it’s properties into consideration. This is a general overview of my experience using cat 5, and cat 3 wire for antenna feed lines. It is something I have been doing for quite a while for receive and TX antennas, and with good results, so I thought I would post my general experience doing so.
I have searched the net and this forum, and am surprised no one has really discussed it.
