No difference in reception at my location at Stanhope Gardens. Very strong signal on Digitech Dab+ fm tuner through fm Omni antenna.
3 bars out of 5 on Pure Move Dab+ fm portable with headphone cord as antenna. Same strength as before when at full power. No intermodulation.
What are the specs of the test on the main Fm antenna? I understand you would not be going out at 50kw / 25kw directional.
