7 element 144MHz EME Yagi OWL-GT Super-Light Yagi

Description

A 7 element OWL-GT (Optimised Wideband Low Impedance) Super-Light Yagi for 144-145MHz - 2019 model

FOR HORIZONTAL  MOUNTING - Now with more gain!

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, ensuring they work as well as our software model predicts.

Specification

This antenna is made with a 1/4 inch (6.35mm) solid rod elements and with the driven element being and 1/2 inch (12.7mm) with 3/8'' (9.525mm) loop ends. 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.

Here's a photo of 7 ele owl being evaluated at Ventnor on Saturday. Works really well - it was interesting to compare it against the 5 ele owl. Certainly about the same forward gain as a 9 ele tonna, but greater beamwidth and less lobes.
