My antenna is a 4 x 29el. DJ9BV array. All elements are made of 4 mm aluminium and they are mounted insulated through the boom. Each antenna is 8.5 wavelengths long (6 m). The stacking distance is 1.7 m. The H-frame is also made of aluminium and the whole system is lightweighted and can be carried by one man. The mast is telescopic and can be raised 3 additional meters for operation.
