Specification

This antenna is made with 3/4 inch (19.05mm) centre elements and 5/8 inch (15.88mm) outer elements and 1/2 inch (12.7mm) tips. The OP-DES end sections 3/8 inch (9.525mm). The antenna has fully insulated elements which will ensure continuous, high performance for many years to come. Boom to mast brackets are included with all antennas which will support 2 inch (50mm) masts.  Boom is 3 inch (76.5mm) square 10SWG aluminum (3.2mm wall).

Our antennas are constructed with the best quality materials in order that 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 of what they should be, ensuring 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 of our antennas have least effect on performance and pattern degradation.

  • Marine grade Stainless Steel Fittings
  • Original Stauff Insulation clamps
  • Mill finished boom and elements for highest levels of accuracy
