4 element 14MHz OWA-HD Yagi (9.8m)

Description

A Heavy Duty 4 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 (32mm) 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!

This antenna has a flat SWR curve covering 14.000 - 14.350MHz at 1.1:1 SWR.

Specification

This antenna is made with 1.25 inch (31.8mm) tube tapering to 1 inch (25.4mm) tube followed by 3/4 inch (22.25mm) and 5/8 inch (15.88mm) outer elements with. 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) (larger available upon request) masts.  Boom is 1.75 inch square 10SWG (3.2mm wall) aluminum with Kevlar boom guys and stainless steel turnbuckles for guy adjustment. Wind loading over 100MPH.

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 (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.
