The active antennas cover LF and MF and even HF. Their output is low-impdeant and one could build e.g. two source followers on the back end. Then you can connect two receivers which don't 'see' each other. If you don't like to build a separate active RX antenna (i would do so!) then you could also use the large TX wire. Then you can even afford a double or triple RC lowpass filter in the front end to attenuate the strong MF broadcast stations (if there are still any). 73, Stefan
