..the first - for me.
Modulation very good antenna could be a bit better at 145MHz is quite well adapted to -12dB. Only the second harmonic suppression leaves to be desired. This is (depending on the band) between 27 - 33dB. An adaptation of the low-pass filter (with me with 30pF - 2x15 par.) Results in a suppression of 57-70dB.
