# Is there a suitable alternative to using a metal pole to mount a vertical yagi apart from wood and fiber glass?

Does anyone know if a non-metallic pole approx. 4 m long is available that i can use to mount a vertical 10 m 4 element yagi ? that is not wood, PVC or fiber glass as these are either too heavy or not strong enough. My location is Melbourne in Australia.

• Unless you are willing to go with carbon fiber, I believe the strongest synthetic common non-metal is fiberglass. – Chris K8NVH Oct 11 '19 at 0:13
• I'm guessing you do not actually want non-metallic but non-conductive? Carbon fiber is a good conductor. What is your issue with fiberglass? the mast e.g. of a windsurfing board is plenty strong. – loonquawl Oct 11 '19 at 5:56

• Short pieces of metal have very little effect on the antenna. If the section connected to the boom is << 0.25 $\lambda$ or an unconnected section is << 0.5 $\lambda$, it won't couple much to the antenna. – tomnexus Oct 15 '19 at 14:43
