80m: RQ-280: 2 elements quad with parasitic reflector, rotary. Switching forward/back and three pre-tuned frequencies in the band. Elements are capacity loaded (perimeter of each loop is 60m). Quads are spaced with 12m, boom length -- 16m, boom weight -- 100 kg (aprox.). Height of top above the ground is 41m. Mounted on the survey radar rotator placed on the top of sectioned steel tower. Was built in September 2002, tuned in 2003. See video -- moments of antenna assembly (500 kB, DivX codec required).
