EFHW Un-un Mount with Cable Winder

This is a toroid mount that i developed for my heavy duty EFHW antenna featuring huge FT 290-43 toroid with 73.5 mm diameter. 

Although I am using this for a 40m EFHW antenna, this could also be used for 1:9 ununs for EARCHI/Random wire antennas or Rybakovs with 1:4 ununs. I printed this with ABS and 0.6mm nozzle, so it looks a bit ugly since I only care about the functionality. It has 3 samll and 1 big hole on each arm to run wires through, and 6 small holes opposite of the SO-239 connector so you can stabilize the cable going from toroid to the antenna.

I also hot silicon glued two terminals to different positions so i can easily change my antenna cable and counterpoise in case. 

There's 20m of silicon lined 1 mm2 wire on just one side of the winder, so if you really want to, it can carry up to 40m of wire for 3.5MHz. All the anntenna weighs 537,3 g with this setup. 

I suggest printing with heat resistant material since the toroid can get pretty hot with digital modes/CW and high power.
