• 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!

G0KSC Writes for the ARRL in the 2106 Antenna Book

The success of the G0KSC antenna designs in both amateur and commercial worlds has been marked with proven low-noise properties and wide band performance (not just SWR) in one package. North American hams adopted the LFA with open arms which results in the LFA being the most frequently home-built antenna in the USA. This did not go unnoticed by the ARRL who asked G0KSC to contribute to the VHF/UHF section of the 2016 ARRL Antenna Book. 

I have removed a lot of the old ideas and concepts, replacing them with modern and proven facts along with providing detail information of correct software model to built antenna principles and even a whole heap of new designs for the reader to self-build.

NCJ interviewed me too and this will appear in the next edition and some of the above mentioned material is discussed. Finally, for all those QST readers, I have committed to 6 antenna articles next year too and will release some of the more exiting and yet to be published designs.

As a footnote stay tuned to DUBUS magazine, in the next issue I will conclude my most recent design and build article there too, should keep you occupied over the winter holidays as it is released in December!

Justin G0KSC


I took some time out (G0KSC) this afternoon to install a new 4 element LFA for 50Mhz in Spain this afternoon. The new, wide-spaced designs (this one 3.9m long) produce a combination of excellent gain, F/B and and bandwidth too.

10.6dBi, 32dB F/B and clean elevation pattern too? It can only be another G0KSC design.



This and other high gain LFA and OWL designs will appear in the 2016 ARRL Antenna Book. Watch this site for release date information.
