• G0KSC designed 3el, 40M & 6el 20M (Force 12)

    This antenna uses the G0KSC OP-DES design on both 40m and 20m to provide full-band coverage on each.

  • 6 x 7el WOS 50MHz LFA Yagi

    175' fully rotating tower and 6 x 7el 50MHz WOS LFA Yagis at W7EW

  • 3 el 24MHz LFA Yagi by InnovAntennas

    Serious low-noise performance for the HF bands too!

  • 4 x 6el 50MHz LFA Yagis @ DL5WP

    Those that do their research and want low noise Yagis choose G0KSC designs!

  • 4 x 11el 144MHz LFA's @ F3EGA

    Excellent G/T figure antenna array ensuring F3EGA can hear and be heard!

  • G0KSC Monoband 14MHz Log Periodic

    With a boom of just 2m and F/B in excess of 20dB including full-band coverage, this is a super-compact Field day antenna!

  • 4 x 24el 432MHz LFA @ PA2V

    PA2V selected G0KSC LFAs (built by InnovAntennas) when he wanted the very best in EME performance!

  • 4el 27MHz LFA Yagi by InnovAntennas

    A 4 element 27MHz LFA by InnovAntennas. The LFA can handle 20KW plus and does for many radio stations, commerical and hobby!

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 QRZ.com.

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!
