40m Antennas.

The 40m band is the serious DX band after dark. When the high bands close, 7 MHz carries intercontinental paths right through the night, and in the major contests it is where winning scores are made or lost. Most operators settle for wire antennas here; a rotatable beam on 40m is a statement of intent, because everything about the band is big — full-size elements approach twenty metres from tip to tip, and the boom carries loads that would flatten a lightly built high-band Yagi.

That scale is exactly why the engineering matters. Our 40m designs pair the LFA's closed-loop driven element with tapered, truss-supported elements sized from wind-survival calculations rather than optimism. The closed loop earns its keep on receive too: 40m noise floors are punishing, and the LFA's rejection of off-axis and static noise makes marginal signals workable where a conventional feed hears only hash.

The range runs from compact two-element designs for a single-tower station through to full-size multi-element arrays built for serious contest and DXpedition work.
