Kenwood TS820S RF Plate Choke Sweep




OCF Dipole (80-10 meters) Return Loss Sweep. Note: 1st deep notch at left is 80 meters followed by 40, 20, 17, 12 and 10 meters. The antenna works well on all the bands with exception of 15 meters which you can see has a -5.61 dB return loss or a 3.2 to 1 vswr. Also, 30 meters is not a good performer. The antenna will also work on 6 meters, but I didnt extend the sweep there.
