I am trying to fit the antenna on to the scanner of a new 1935 and it will not seat flush with the scanner. I read in the FAQ that the foam block is supposed to remain in place, but there doesn't seem to be enough room for it to fit between the waveguide fittings. I could probably snug it down with the bolts, but I am afraid to force anything until I know for sure. I was careful to slide the antenna sideways and down onto the scanner to insure that the foam is in the gap, but it pinches between the waveguides and won't seat completely. Do I just bolt it on down, or am I doing something wrong? And, is that gap between the waveguide assemblies of the scanner and antenna normal?
