Planning on installing a DRS12ANXT radar on a 27' center console and wondering if I will see any noticeable differences if I go with a 3.5' antenna vs a 4'? I can fit the 3.5' right now but if I go with the 4' I will have to move some other things currently mounted on the top. I obviously know the narrower beam width would be better but is it worth all the extra work?
