I have demonstrated a Carbon Fiber Yagi. I did fudge a little bit, and the first inch or so of the driven elements was brass tubing. Hard to solder the coax to carbon fiber. Carbon fiber is electrically conductive and behaves just like Aluminium Carbon Fiber Rods make nice Yagi Elements. Nearly 50 years ago the 10 foot dish used on the Voyager spacecrafts were made out of Carbon Fiber. They were taken to the antenna range ..... and passed specs. As a weight savings there were NOT metalized. Just got some 3D printed clips for the Arrow booms. These are designed to hold an 11 element 1269 MHz Yagi 45 deg to the 145 and 435 MHz elements adding L-Band.73 Kent WA5VJB

If anyone has the CF boom and would like to 3D print clips to fit the boom as the original, see here : https://www.thingiverse.com/thing:4728323 I remixed the original design and widened the clips. RG58 is still only supported and working on expanding to different coax sizes like RG8X or LMR240UF KO4AQF -----------------------------------------------------------
