Hi Justin (G0KSC),

I am writing to thank the design of the OWA 10m / 5 elements antenna that is available on your webpage.

We built the antenna and it showed excellent results:

Without the choke:

SWR = 1.1 from 28.000 MHz to 28.300 MHz

SWR = 1.0 from 28.350 MHz to 29 MHz.

R = 55 Ohms and X = 0 Ohms. (on MFJ-259C)

With choke:

SWR = 1.0 from 28 MHz to 29 MHz.

R ranging from 47 Ohms to 57 Ohms with X = 0 Ohms to X = 5 Ohms, depending on the frequency.

Let's now build an OWA for 15m / 5 elements.

We thank you and invite you to visit our website (PR1M) on

Many thanks Justin.

Current design G0KSC antennas are ONLY produced by InnovAntennas in the UK and Hy-Gain / Cushcraft in the US. NO OTHER company makes current design LFAs

More and more EME systems are appearing as a result of the solar cycle position and the continued craving for DX! The LFA provides a quiet platform for VHF and UHF along with provision of gain enough to provide the edge needed to excel. SM6LPF chose the 6 element LFA Yagi as the basis of his EME system and took my advice on loss-saving routing and cable provisioning within his setup. The result being this rather nice forst for him on 6m:

''The antennas work very fine, just worked ZL3NW on the moon for a new continent.''

IIf you need help, advice or just would like to discuss and confirm your selection of design, drop me a line I will be happy to help!
