There are not any baluns on these antennas. If I remember right, they use 75 ohm coax on each bay (odd multiples of quarter wave length) and 35 ohm coax on the feed (again odd multiples) to match the impedance to 50 ohms. This info was on the group a while back, somebody must still have it.

Would a close up pic of a DB304 work for your needs, or I have the DB420 there as well.Mathew

I have been studying the db stacked array and the
bayed array seems to use unbalanced dipoles as the
radiators .I have tried to find a close up view of a
single dipole so I can confirm my ideas.
If anyone has some good tech info on these antennas I
would appreciate the info.
It would make sense to " by-pass " the need of baluns
for each dipole -cost and balun loss?????
