10 element 144 Mhz EME Yagi
A 10 element OWL-G/T EME & Weak signal Yagi
(Optimised Wideband Low Impedance)
FOR HORIZONTAL MOUNTING
This is another fantastic design by Justin G0KSC. A low impedance Yagi provides excellent performance, however, traditionally, low impedance has meant narrow band.but this design gives coverage of the full band 144 - 145 MHz
This antenna has very close element spacing, to increase the stability of the OWL over traditional low impedance Yagis. Additionally, it has been optimised with a folded dipole element who's impedance is a cool 50 Ohm, so again no matching device is needed!
IDEAL PORTABLE, SOTA or EME !!
The OWL G/T has been designed to achieve high gain levels while still producing very respectable sky temperature figures. This combination has resulted in class-leading G/T performance being achieved (reference VE7BQH list). For this reason, if you are a weak signal ham, want to work EME or MS or just want to hear weak signals others can't, this could be the antenna for you!
Designed with the very latest modeling 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.

This antenna is made with a 1/2 inch (12.7mm) and 3/8 inch (9.525mm) diameter tube OWL loop and 1/2 inch (12.7mm) elements with a wall thickness of 1.2mm. 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.
