... Now the antiresonant point will be between 100 and 200 ohms resistive which allows me to feed it directly from a 50 ohm transmission line (3/4 andrews) with negligable losses as the mismatch is resistive. __________ Art - An antenna with an input impedance of 150 + j 0 ohms has a reflection coefficient of 0.5 (50%), a return loss of 6.02 dB, and an SWR of 3:1 to a 50 ohm source. Probably not many transmitters would be happy with that magnitude of load mismatch. Do you maintain that the losses defined by these parameters are negligible to amateur radio operators? RF |
