[back to W1TR Antennas and QTH]
The 20 thru 10 meter dipole is constructed from #10 stranded insulated wire available in most hardware stores.
The feedpoint uses an 8 inch long section of 2 inch diameter PVC pipe. A section of wire joins the elements at either side of the feedpoint to avoid the inductance of square knots that I use on lower frequencies. The coax loops through the PVC pipe to provide strain relief and is connected to these element joining wires. Mechanically, the element wires are tied using a square knot to the PVC pipes at either end and also to rope which is then tied to tree trunks after going over the tops of trees. The “springiness” of the small branches appears to help the wire antennas survive 60 knot winds with little or no damage. As noted below, I am not as happy with the performance of this antenna as some of the others in the antenna farm!
