160 Meter Vertical
Constructing a 90-foot top-loaded vertical antenna for 160 meters using aluminum irrigation tubing.
Description
A 90-foot tall top-loaded vertical antenna for the 160-meter band is detailed, constructed from aluminum irrigation tubing. The design incorporates four sets of four guy wires for structural stability, essential for an antenna of this physical size. This monoband vertical is optimized for low-band operation, providing a robust solution for DXing and contesting on 1.8 MHz.
The document includes specific construction methods for assembling the aluminum irrigation tubing sections and securing the guy wires. While a full NEC model is not explicitly provided, the physical dimensions and construction materials are sufficient for replication by experienced builders. The antenna's height and top-loading configuration are critical for achieving efficient radiation on 160 meters, particularly in minimizing ground losses.
