K5IN, The antenna you have is a DB-406. They are a old design and were fairly narrow banded (450-470). As a rule they do not make the Ham band with any kind of return loss numbers that are desirable for use as a 440 repeater antenna. With the loops orientated the way they are in your picture the old DB books showed the antenna to have a gain of approx 10.5 db. You will most likely need to replace the harness, but check it out thoroughly, it just might be one of the rare ones that will work well on the 440 band.

It appears to be 3 dipoles fed on the bottom half and 3 on top. Harness definitely appears to be factory made. Hopefully the pics will help someone to identify this for me. I have more pics
