OK. Thanks anyway. Just thought there might be some experimentors out there in RF land. Do you think a 420-430 antenna work on the 3rd hanmonic, similar to using a 2 mtr. antenna with a 440 transmitter, as I have seen mentioned here on occaision ???? There isn't a lot out there in base/rptr. antennas in the Amateur or commercial market for 1.2 GHz. unless it is special order.
