I know DB made a dual band 150/450 folded dipole antenna (bottom half was either a DB-222 or the bottom half of a DB-304 and the top half was a DB408 or top half of a DB-420), which is no longer available. Does anyone recall whether it was fed with one feed line or two ? I think it was 2 but, I can't recall the dipole configuration (singles on opposite sides going up, or pairs at each level).
I would like to combine a DB-224E (138 -150) with a DB-408 or DB-420 (450-470) on a single mast, or split the antennas at the mid point and make 2 antennas with the VHF on the bottom and the UHF on the top, and the reverse on the second antenna. Has anyone tried this ? What were the results ? The numder of feed lines (1 or 2) to the antenna is not an issue at this time. The combined antenna would be for a 2 Mtr./440 D-Star application becuase of limited tower space available. Comments appreciated Doug N3DAB
