Description

I wanted to find a way to mount my PAC-12 horizontally as a dipole since it is tapped for M10 on both ends.  Since I had a 24' extendable painter's pole available, I based the mount on standard ¾" ACME threads.  This device simply screws onto the end of the pole.  Once attached, you can place the PAC-12 base into the cradle and zip-tie it on. 

 

I printed my test model at 20% Infill with Bambu PETG-CF.  Do not use PLA as this will be outdoors.  You want a plastic that will stand up to UV as well as provide strength since this will be handling torque loads from wind on the dipole.

 

My initial test worked, but I feel like the PETG-CF was a bit too soft.  I will try ABS or ASA when I get a chance.  Please let me know if you have any luck with a different filament type.

 

So did it work?  Absolutely.  I didn't take any scientific measurements, but I did make a quick POTA contact to a park in Florida (from Arkansas).  It pulled in a better signal than my 29' random wire attached to the same pole on 20 Meters.  I did not leave it up due to not having any guy wires on the mast.  you can see it leaning in the pictures.  I'll try it again once i get some ground spikes.

 

Lastly, use this file at your own risk and please be safe.
