So2r Antenna-to-Antenna Coupling

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.
