This is machined from 6.35mm marine-grade high-density polyethylene that is UV protected and good for high-power.

This is inert to RF, particularly HF and an ideal companion material to make insulated components for HF antennas.

Supplied is ONLY the blank. You will need to supply yourself some appropriatehardware (6mm / quarter inch bolts, washers and nuts, a two rope thimbles for strain relief between your radiating element and the plate and perhaps some ring connectors to solder to your elements (and some 450 ohm ladder line).

The real benefit to this component is that your 450 ohm line is not tensioned directly near the fulcrum where your 450 ohm line will enevitably be wiggled about. The length of the cut plate means that your feeder will have a much easier time over the years.

Cable ties are optional.
