3 element 50MHz OWL Super-Light Yagi

Description

A 3 element OWL (Optimised Wideband Low Impedance) Super-Light Yagi for 50.0 - 50.4MHz

FOR VERTICAL OR 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!

Designed with the very latest modelling software packages costing 10's of thousands of pounds, not 30 year old software costing around $100.00!! Accuracy in model and real-world performance assured.

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.

The super-light OWL's have elements connected and through the boom with a single securing bolt (3el rear mount OWL featured above)

Specification

This antenna is made with a 1/2 inch (12.7mm) and 3/8 inch (9.525mm) diameter tube OWL loop and 3/8 inch (9.525mm) elements with a wall thickness of 1.6mm.  Parasitic elements are tapered, 1/2'' to 3/8'' tube ensuring high performance for many years to come. 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.
