A 5 element OWL (Optimised Wideband Low Impedance) Super-Light Yagi for 144-146MHz

FOR HORIZONTAL mounting

The G0KSC OWL is another fantastic design by G0KSC. Every ham knows a low impedance Yagi provides excellent performance. However, traditionally, low impedance has meant narrow band. G0KSC developed the OWL to have very close element spacing, this has increased the stability of the OWL over traditional low impedance Yagis. Additionally, the G0KSC 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 again (and as with all InnovAntennas Yagis) no matching device is needed!

IDEAL PORTABLE OR SOTA USE!

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 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.

 

Ian G0CNN made this excellent video which highlights how simple the OWL is to construct: 

on 2m OWLs elements are friction-fit to reduce time of installation and weight. see close-ups of this 70cms OWL Ultra for examples:

Specification

This antenna is made with a 1/2 inch (12.7mm) and 3/8 inch (9.525mm) diameter tube OWL loop and 6.35mm (1/4") parasitic elements.  Boom is 3/4" inch. This antenna is not made cheaply, it is made to perform and to do so for many years.

No figures are made up here as they are in some Ham Radio adverts, all performance figures are verified in the very latest software simulation packages with some antennas being professionally confirmed on an antenna range.
