A new manufacturer has entered the beam antenna field with a six and ten meter beam. The six meter beam has six elements on a 15 foot boom which is slightly arched to compensate for the sag one would normally expect in an antenna of this length. There is some weight to be reckoned with too, for the elements are all one inch aluminum which should result not only in a very sturdy and long lived beam, but should give a wider bandwidth than beams with smaller diameter elements. Plastic caps are...
