I got this 3 EA. BNC-FEMALE PANEL RF CONNECTORS * NEW * TEFLON INSULATED. * HAM RADIO * QRP | eBay last spring to go with my KX2. It tuned it but not very many contacts maybe due to the 31’ of wire. I’m about to make my own 9:1 unun shortly and plan to try and run it with at least 58’.
Here is more info on them. Random Wire Antennas - Best Lengths To Use For Random Wire
I use 25’ of RG-58 instead of what most use (RG-174) so not sure where that is going to fit in.
