Output Impedance 50Ω Overall Performance (Antenna Element, LNA) Center Frequency(MHz). Place a 1:1 Balun on the Antenna end of the Feedline. With my antenna analyzer I was quickly able to tune the loop to the middle of 30m by trimming the coax. NOAA Weather / Railroad Band 160 - 162 Mhz J-Pole Antenna. However, when I operated on the lowest ham band, 160 meters (1. losses on 160- and 80-meters, and will preserve the compromise SWR and relatively low SWR-related losses of the original antenna from 60-10 meters.
