For a Decathlon Caperlan 6m Travel fishing rod that I use as a mast for a ham radio antenna for SOTA/POTA.
One part is to keep the mast upright (use on the lowest element of the fishing rod).
The other parts are to hold the antenna wire on the second highest element of the rod. The top most element of the rod is quite flexible.
There are two variants of this part:
This model does not include the parts to tension the wire, only to fix the wire on the mast and to hold the antenna on top of the mast. I am using the tensioners from swiftthefox https://www.printables.com/model/136656 and from terminalsump https://www.printables.com/model/764190 for this.
The author marked this model as their own original creation.
