Better a small one than none at all...
Compact leightweight 3 band antenna for 10, 15 and 20m. Approx. 3dB less gain than a full sized 3 element beam, thats about a half s-meter level. Firs on a small semi-detached house, without touching the neighbours airspace...

Still a litlle bit smaller than the Mini-2000 beam for really restricted space, available with two or three elements. Slightly less gain and bandwidth, some alignment work requried. The spreader at the end of the elements act as a sort of top load on a groundplane, making the antnna even more compact. Mounting hardware stainless steel - as with any ZX Yagi.

Review about G4MH mini beam from "FUNKAMATEUR" 5/2001 (german, ca. 100 KB)G4MH description (ca. 100KB)
Five bands in a small, rotateable beam? Without lossy traps? Butternut has done it again... Especially for the amateur with restricted space this antenna yields a significant improvement over omni directional verticals. A good front/back and front/side ratio is helpful in suppressing QRM. For best performace this antenna should be erected at least 9m above ground. PL connector with stub feed, coax feed can be any length.
