RJ45 (or RJ11) plugs?
Stainless studs with wing nuts and spade connectors?
This.
I also prefer screws/nuts over banana plugs. Even if a wire breaks, you can easily fix it.
In this case M4 brass screw and a knurled nut (steel, as I didn’t have any brass ones at hand).

Thank you for the answers. I used to use ring connectors and wing nuts to connect radials before switching to banana plugs, and it works well. I was hoping for some connector that is similar to banana plugs, or at least with a similar effort to connect, but that is slightly stronger. It does not need to be sufficient for permanent installations.
RJ11/RJ45 is an interesting suggestion. Do you know if it can handle 100 W RF?
This gives you the convenience of banana plugs and the backup solution for screwing in one. This gives you the convenience of banana plugs and the backup solution for screwing in one. And with the stackable banana plugs, you can plug several radials into one socket.

Hi all,
After reading all these stories, I couldn’t resist and also ordered one of these whips.
It took me some time to write up a report, but I made two versions of the “cheap Chinese vertical” … see report with lots of pictures on my blog:

They are quite nice. The ones I have can also screw in ring connectors, but I have not used the stackable banana plugs.
Well, my trialling the antenna hasn’t been quite as labour intensive or ingenious as ON7DQ. I took the easy way out and purchased a 40 meters coil to go with the antenna - as shown in my previous posts - and I went about using it with the FT-981 and a AT-100M tuner.
This is the setup I was using today on a small hummock just outside of the villiage I live in, as I was chasing activations up and down the country plus over to Australia. In this setup, with the AT-100M I am able to leave the antenna fully extended and tune it automatically 40 M to 10 M. Using the MFJ-945E manual tuner I can do the same but can also tune 80 and 60 meters. How effective it will be on these bands I have yet to find out. Next up I shall be trialling the antenna and coil with the Xiegu X6100 and G90 and see how effective those tuners are at making a match. As for the Emtech ZM-2 which I use with the IC-705, I have no doubt it will tune it 80 M to 10 M. Of course you can tune it by adjusting the length, but with a tuner it makes things a lot simpler and quicker to swap bands and you have the advantage of still having all of the antenna in the air.

I made a 40m loading coil for this thing with a couple of mounting options. Will post to Printables when I have a free minute (this evening?)
