I have a pushup mast that I use for my activations. I recently broke the PackTenna 1:1 balun that I had and found out that they have a new model that I ordered. The shape is different and I am having difficulty attaching it to the top of the mast.
How do you attach yours?
A standard current balun wound on coax does not need any additional support. But if it did I would use a reusable cable tie.
Velcro computer cable tie as strain relieve is what I use.
I have a commercially built SpiderBeam-Aerial-51 UL-404 antenna which has a 4:1 ferrite core BALUN in a plastic box which is filled with epoxy resin I believe. To mount that I have screwed two small net curtain hooks in the back of the box and that slides down the mast to where the mast is as wide as the hooks.
YMMV but this has worked fine for 5 years so far.
