The model 41.5-7 Yagi has been specifically designed for ONE MHz bandwidth segments between 40 and 50 MHz. We have several models that split the band like model 47-7 for instance which covers 46.5 to 47.5 MHz. Each antenna produces excellent gain and good match across it’s one MHz bandwidth. The computer aided design produces a clean pattern improving signal to noise ratio and wasting less transmit power. High grade, low corrosion aluminum (6063-T832) is used for both elements and boom and comes standard with no finish. For seaside or corrosive environments, optional alodined, anodized or powder painted finishes are available. Elements mount on CNC machined 6061-T6 aluminum ring clamps and stainless steel hardware is used throughout the assembly. All the elements are grounded to the boom for lightning and static protection. A broadband 'T' match and 4:1 balun couple energy efficiently to and from the antenna. The matching system handles 1 KW continuous transmit power. Higher power models using ‘HN’ and ‘DIN’ connectors are available and will handle up to 10 kW.
