Used to attach your telescopic fishing rod to the end of a tripod or post for portable / QRP ham radio operations. Also includes a tip that can be slid over the top of your rod to connect a single antenna cable/balun, or a dipole type.
My tripod end is 1" diameter, and the fishing rod is 1.04" at the very base, and 1.0" up where the top bracket attaches (not that the model needs to be that precise….).
For hardware, use ¼" x 1.5" bolts, and press the nut into the knurled holder (for tool-less field operation). I made it very tight, so you'll need to hammer in the nut or warm it with a lighter or soldering iron & press it in (this way the nut won't fall out in the field).
Otherwise, see the attached Fusion file to modify it as you need.
