Dipole mount for weather satellite reception

thingiverse

The purpose of these files are to provide a means of mounting two aluminium rods to a length of 32mm waste pipe. Why? To form a dipole antenna for the reception of NOAA satellite data on the 137MHz band using an SDR receiver. Basic construction of the dipole is described by Adam-9A4QV in his blog, here http://lna4all.blogspot.co.uk/2017/02/diy-137-mhz-wx-sat-v-dipole-antenna.html What I required was some sort of mounting arrangement so that I could fix the dipole to a length of wood (to enable me to raise it into the air) and also rotate it in order to align the rods in a N-S direction. I also wanted something reasonably modular and portable. The basic rod mount is essentially my copy of Tysonpower's thing but I went a little bit further by adding a method of fixing the choc-block connector as well as a mount for a coax connector (SO239) and a cover for this which slips over a 1m length of 32mm white plastic waste pipe. I used ABS for this project as the unit will sit outside and I didn't want PLA to start deforming should the sun start to shine here in the UK :-) Print settings are not too critical - I used a layer height of 0.25mm and an infill of 20% on my Nophead Mendel90.
