25mm tube to 19mm Box - printed in ABS and PLA - Both ok.
19mm Box to UHF Base, printed in ABS and PLA - Both ok.
Designed to fit 25mm "Jpole" (aka Hockey Stick) poles.
Typically the kind of thing you see attached to awnings or eves, with a TV antenna attached.

The desirable cross-arm would be aluminium 19mm box tube.
You will want a handfull of assorted stainless 3mm nuts and bolts as well.
I designed this to use a standard UHF antenna base with 10mm square "keyway" on the stub.
It's not hard for me to design different mountings to your need - or you can download inventor part file as well.
Inventor files attached for the budding modding enthusiast.
More info to come as I print and test them.
Currently testing in transparent PLA....
ABS versions to come later.
Finally - remember not all printers are equal, not all operators are pro's.
Your results may vary, but my models measure up to spec.
