Measuring Attenuation for Adjacent Band Coupling
When the Gen 5 modifications were complete, the antenna-to-antenna coupling of the various So2r adjacent band combinations were measured from the shack with the VNA. Results in the table below.
As predicted by EZNEC, the worst-case combination is 20/15. However the coupling here at -36 db is much less than the model. I think that's likely due to the fact that the model does not include the stubs which are used in the decoupling system so their action is not considered by EZNEC.
