4 Element OWL (Optimised Wideband Low Impedance) Super-Light Yagi for 144-146MHz

Designed with the very latest modelling software packages. Accuracy in model and real-world performance assured.

Improved Performance

A low impedance Yagi provides excellent performance. However, traditionally, low impedance has meant narrow band. the OWL has been designed to have very close element spacing, this has increased the stability of the OWL over traditional low impedance Yagi’s. Additionally, the OWL has been optimised for a 12.5 Ohm feed point impedance (with traditional split dipole). With the split dipole swapped for a folded dipole, impedance is now a cool 50 Ohm so no matching device is needed

Multiband, Performance-Busting Design

Despite its rigidity, the OWL is extremely light weight and this means even in strong winds, snow and ice the OWL will hold its own.

The antennas are constructed with the best quality materials in order that the best mechanical construction can be achieved, 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 antenna is made with a 1/2inch (12.7mm) and 3/8inch (9.525mm) diameter tube OWL loop and 3/8inch (9.525mm) elements with a wall thickness of 1.6mm. high performance for many years to come. Boom is 3/4 inch. This antenna is made to perform and to do so for many years.
