This loss is about .11 db/ft, little more than RG58. If one used RG223 (double shielded RG58) the loss would be about the same.
Going to RG214 loss would be .05 db/ft, an improvement. All this is at 400 MHz. At 400 MHz the .11db loss would be .63 watts from 25 watts. I don't think much improvement would be realized if replaced. Also not sure all the other specs of the cable; double shielded, silver solder, etc????? This would also be factors I would consider. I do like the idea of removing the cable and replacing a single cable from each rig long enough to get to the duplexer, but to simply replace the 10" cable with another would not be of much concern as loss goes. If desense problem then this is another issue. 73, ron, n9ee/r
