Specification
The 17m element is made with a six section taper starting at 25.4mm (1') finishing at 9.525mm (3/8''). The 15m section has 5 tapers starting at 22.25mm (7/8'') and finishing at 9.525mm (3/8'') while the 10m element has 3 sections, the centre being 22.25mm (3/4'') with 15.88mm (5/8'') tips. All elements are insulated and stainless steel hardware is used throughout.

Our antennas are constructed with the best quality materials in order the best mechanical construction can be achieved, not the cheapest and most profitable! Even a digital caliper is used (with an accuracy of .01mm) to measure the elements during production to ensure they are within 0.2mm (on critical bands) of what they should be, this ensures they work as well as our software model predicts.
Note: much development time has gone into our antennas, not just on basic electromagnetic design, we are able to model the effect of insulators, booms and other objects to ensure the make up or our antennas have least effect on performance and pattern degradation. More information can be found here
- Marine grade stainless steel fittings
- Original Stauff Insulation clamps
- Mill finished boom and elements for highest levels of accuracy
