Now tested and working!**Added 25mm to 25mm Tube attachment (6-9-2015)Added 25mm to 20mm Tube adaptor (6-9-2015) 25 to 25mm - printed in ABS - not tested on PLA yet. 25 to 20mm Printed in ABS, not tested on PLA yet 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. see this image: https://www.telcoantennas.com.au/site/sites/default/files/imagecache/product_full/antenna-J-pole-hockey-stick-gutter-fascia-bracket-mount.png 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.
