6 element 14MHz OWA-HD Yagi (21.1m)
A Heavy Duty 6 element 14MHz OWA (Optimised Wideband Array) Yagi
The OWA is one of the traditional HF antennas to have if you are looking for wide band, stable performance. The HD Version is made with 4 stage tapered elements starting at 1.25 inch (31.8mm) tapering down to 5/8 inch (15.88mm) at the tips. InnovAntennas use the latest in Electromagnetic Design Technology to ensure the very best results and the InnovAntennas OWA Yagi is proof of that!

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 (VHF).
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.
