AO analysis; 9.7db F/G 8.2db F/B 300 ohm feed impedance - 286 + j 18 ohms SWR = 1.08:1 The antenna has a 300 to 75 stripline transformer built into the feed point making the transmission line (RG-6) a better way to send the signal to my FM tuner. Add three (3) ferrite line chokes (apx 1000 ohms) at the feed point to further attenuate the common mode signal.
