Hi Iain, 


Simply use a relay at the base of your inverted-L to disconnect or 
detune the antenna when you're receiving

Hi, 



I have limited real estate. 



I can put up an RX antenna either: 



1. Away from the inverted-L vertical section to reduce re-radiation to 
the Rx antenna. 

or 

2. Away from the END of the inverted-L to reduce re-radiation to the RX 
antenna. 





Not both unfortunately. 



So should I site the Rx delta shaped loop for 160M away from the vertical 
high current or the high voltage end of the inverted-L?
