Hi, I have a quired a used DB-420B antenna. My plans are to use it for 
my 443.65 repeater. After a close inspection I have found that the 
previous owner must have tried some "tuning". All of the spacings in the 
vertical plane between elements are different dimensions.  So, I have a 
few questions:

1. Can anyone tell me what the center to center spacing is supposed to be?

2. Would it be of any benefit to change the spacing to reflect the lower 
operating frequency?

The antenna has a good SWR at my freq. but I am sure the pattern cannot 
be at its best with the varied spacing. Any help appreciated.

Thanks,

Bob
