Updated V2.0 2E0ERO Magnetic Loop Antenna Base and Control Box

Version 2.0 Update: totally redesigned threads created in AutoCAD and test fitted to several commercial painter poles. The geometry was tweaked to match the antenna base better.

I've included an STL of just the threads if you need them for another project. The thread body is 30mm tall x 29mm dia.

Also, I damaged the control box and had to rebuild it. Detailes are included for that too, along with parts list from Amazon.

In the picture of the finished part, the blue mounting plate is highlighted in the yellow oval. The rest of the 3D printed hardware in this are made by 2E0ERO antennas and it comes fully assembled when you buy one.

This is a mounting plate alternative design for a 2E0ERO magnetic loop antenna baseplate adapter (like the original) with female threaded body for a standard painter's pole or broom handle with a 3/4-5 TPI ACME thread. I mainly use the antenna indoors but also for portable OPs only (capacitor is open/air) and I mount the pole in a patio umbrella stand. This allows me to get the antenna up to 8'-12' easily, which is plenty high enough for a mag loop (and out of reach of kids/passers-by). Keep in mind, while transmitting (even at low power) you have several thousand volts on that capacitor!

Mag loops have high Q and have natural noise rejection which pairs well with digital modes (like PSK31/FT4/FT8/JS8). The 2E0ERO loop is rated to 30W and I use it mainly with a Xiegu x6100/G90. The antenna is superbly made and comes with a mounting plate for a standard pipe which I assume is a UK size. The only mods to the antenna I made were adding some grip tape under the mounts for the capacitor motor.

I wanted this to be durable and heat resistant as I use it for field-day/POTA type activities. Also, the antenna was not cheap so I didn't want to risk this breaking so I printed in PETG-CF with 50% infill (adaptive cubic), 6-top/bottom layers, and 6-walls. Less than 70g filament. It is very rigid. Printed with supports (I recommend setting top/bottom support distance between 0.30 and 0.35).

Mounting uses the four M5 bolts that came with the antenna stock mount.

This was designed in Vanilla AutoCAD 2027.

It is shown mounted on an aluminum telescoping painters pole to use as a mast. Unlike wire antennas, for this type of antenna a metal mast doesn't interfere with radiation patterns.
