I live outside of Washington, DC, with lat of 30 degrees North on Americas 98 W..
Normally I point right on and at a given time (like this time when I did a comparison test for you) will receive a 9 dB SNR and signal level of about -107 dBm. I can lie my antenna flat on its back
and loose about 3 dB of SNR (dropping to 6 with a corresponding drop of signal level to about -109 dBm).
I'm using the active antenna with a Dreamcatcher all mouinted in one of the old Lantern Alpha cases with a clear plastic cover. I could never do this with the old patch antenna which only worked well flat in tropical latitudes. Ken
