My first Db was a 410 in the same time period. It had tubular di-poles and tubular stand-off's, not the stamp sheet type now used. It had 8 pairs of di-poles (16 total) and was on a 2 section mast the same as the current DB-420. I don't know what has only 6 di-poles an a 12' mast unless it is a home brew from a damaged antenna. Everything I remember from the old DB catalogs for di-pole antennas was 1, 2, 4, 8, or 16 di-poles. Single sided arrays had 1, 2, 4 and 8 and pairs had 2, 4, 8, and 16.
