Can I mount a Shakespeare 390-1 antenna to the Stepper Motor Mounting Bracket (NEMA 11) ( RB-Phi-272) bracket? The base of the antenna looks like it is drilled like a ball mount for a whip antenna.
The RB-Phi-272 is made for a NEMA 11 stepper motor but if the hole dimension allow to mount your antenna we don’t see why not.
Attached is the PDF file with all the dimensions from the manufacturer.
