Description
The 4 element has set the standard for performance in HF antennas.
With the addition of a 40/30M rotatable Dipole you will have unmatchable single antenna performance. With a 32 foot boom and weighing in at reasonable 106 lb, this antenna is ideal for DXers that want to maximize performance on 20m-6m and still have a dipole on 40 and 30 meters. The 4 element Yagi is configured for maximum gain and solid front-to-rear ratios.
*Due to the confusion about the EIA/TIA wind ratings, SteppIR is now using PROJECTED AREA as the measurement for our customers to utilize when sizing an antenna to a tower. Projected area by definition is the total perpendicular surface area measured in square feet/square meters, that is exposed to wind. To calculate wind load you always take the largest projected area whether that is from the perspective perpendicular to the boom or perpendicular to the elements. In the case of SteppIR Yagi’s, the maximum projected area will always be the sum of the surface area’s perpendicular to the Yagi elements. This calculation is a constant number and will not change regardless of EIA specification changes. Be sure to present this information (along with the weight of the antenna, turning radius, element lengths, height of antenna, location exposure category, locations three-second gust wind speed, and locations maximum radial ice loading) to your structural engineer and/or tower manufacturer so that they can specify the correct product for your antenna.
