Thanks very much indeed Stefan. That turned out to be a very useful test. Here, a little over 20dB in 833uHz, 0.73 fT and 232nV/m, Z = 400 ohms. Huge signal! 0.5dB better S/N on the new active antenna. But thanks to your test carrier, discovered a problem with the phase calibration. -- Paul Nicholson --
