Summary

A simple 120° dipole antenna support for 6.1mm aluminium rod.

I made it to use with and SDR dongle and "listen" to the ISS on 145Mhz.

You have to print the STL twice.

Put the aluminium rod in the 2 part support and drill directly with a 3mm drill bit.

Use 3mm*25mm metallic bolt to do the contact to the coax cable.

Use 4mm*25mm to clamp the two parts.

For 145 MHz, use 50cm aluminium rod.
