Dipole mount for weather satellite reception

thingiverse

The main goal of these files is to provide a way to attach two aluminum rods to a piece of 32mm waste pipe, which measures 32mm in length. Why? To create a dipole antenna for receiving NOAA satellite data on the 137MHz band using an SDR receiver. Basic dipole construction is outlined by Adam-9A4QV in his blog, located at http://lna4all.blogspot.co.uk/2017/02/diy-137-mhz-wx-sat-v-dipole-antenna.html. I needed a mounting system that would allow me to attach the dipole to a piece of wood so it could be raised into the air and rotated for alignment with the N-S direction. The system also had to be reasonably modular and portable. The basic rod mount is essentially my version of Tysonpower's thing, but I took it further by adding a way to secure the choc-block connector as well as a mount for a coax connector (SO239) and a cover that fits over a 1m length of 32mm white plastic waste pipe. I used ABS for this project because the unit will be outside, and I didn't want PLA to start deforming when the sun shines in the UK. Print settings are not critical - I used a layer height of 0.25mm and an infill of 20% on my Nophead Mendel90.
