Trying to figure out why my resonant 20m dipole and my Norcal doublet (both ~1/2 wave above ground level) seem quite a bit less sensitive to RX than a KiwiSDR station ~40 miles away using an 80-10 OCF.
The latter showed 20m SSB hopping while my setup just isn't seeing anything but the strongest signals (-117 dB noise floor on the KiwiSDR vs -120-130 dB on mine)
I really don't think it's receiver sensitivity (I hope it's not).
Does antenna length & height factor into sensitivity?
