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.
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.
