K1PDX Yagi Antenna Kit

Bits and pieces to build a Yagi for just about any frequency and number of elements. Photos show my 4 element GMRS antenna.

Elements are 1/4in round aluminum rods. I threaded the end of the driven element with a die.

PVC is "1/2 in" PVC Pipe (OD is .84")

8-32x3/8 set screws hold everything in place. These may affect the radiation pattern... EDIT: I've added an stl for the McMaster-Carr equivalent screw. I'm now using printed PLA set screws!

Element length and space determined using VK5DJ Yagi Calculator: https://www.vk5dj.com/yagi.html

I was able to print all parts with no supports or rafts (with the exception of the PLA set screw which needs to be printed horizontally with supports and 100% infill).

Fusion 360 file included!
