The 30 Meter Vertical Dipole is constructed from #10 stranded insulated wire available in most hardware stores.
The feedpoint uses a T-section of PVC pipe. The coax loops through the PVC pipe to provide strain relief. Wires are tied using a square knot to the PVC pipe and also to rope which is then tied to tree trunks after going over the tops of trees. The antenna is nearly vertical and hence omnidirectional. The “springiness” of the small branches appears to help the wire antennas survive 60 knot winds with little or no damage.
