My new antenna is a 4X19LLY (I3DLI)
It's 7,75m long and it's really much better on receiving, respect the old system.
It has also a different behavior,respect a tipical yagi.It seems to suffer much less some eme situations.
My rig on eme is as follow:
IC275H +8877 MGF1302 20 db 0.3 nf
DSP2 by IW5BHY and FFTDSP by AF9Y
