Working on a project to add a couple of repeaters to augment the coverage of a single site.
Two companies that have responded have spec'd LMR-400 runs between the repeater and the repeater antenna. These are short runs under 100'. One or two of the three companies are saying that there should not be any desense or noise gemerated. I am looking for technical documentation detailing why LMR-400, of any length, should not be used in full duplex operations. The loss difference between LMR-400 and LDF4-50 is not enough to use loss as the deciding factor, and now the system owner wants documentation to justify spending the money on 1/2" rather than LMR-400.
