Hello guys, I have been trying to model a Dual Output K9AY I.e. taking another output from where the termination is normally placed. Then combine the two equal amplitude outputs with a small phased shift: 10 deg. at 500kHz; 20 deg.at 1MHz; 30 deg. at 1.5MHz, 37 deg. at 1.85MHz. This provides the typical K9AY pattern. However, the gain 8dB higher at 1.85MHz and 22dB higher at 0.5MHz compared to the K9AY. I have yet to verify the model. However, does the model change stack-up?? 73 Andrew Ikin _______________________________________________ Antennaware mailing list Antennaware@contesting.com http://lists.contesting.com/mailman/listinfo/antennaware |
