Hi Mike, LowFERs….you were a busy boy doing all of that testing! It clearly shows that for EAR, your NW EWE antenna is the winner. Would you share with us the details of your 185 kHz. bridge T diplexers? Thanks for the report and the various Argo screen shots. 73, J.B., VE3EAR LowFER Beacon "EAR" 188.830 kHz. QRSS30 EN93dr
