A 3 element compact OWL Yagi

The OWL combines performance and light-weight in one package. Designed for portable use and where there is simply not enough space for a 6m Yagi, this antenna really delivers a punch with just a tiny boom length of just 1.2m (under 4 feet).

The OWL uses an adjustable folded dipole system and has a direct 50 Ohm feed point, no matching device (or associated losses) being the result.

Specification

This antenna is made 1/2 inch (12.7mm) centre elements and 3/8 inch (9.525mm) outer elements (centre sections of the driven element are 5/8''). The antenna has fully Built on a 1'' square aluminium boom with elements passing through (and bolted to) the boom. 

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, 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 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
