A duplexer for 2 meters and 70 centimeters is quite simple in theory, but attaining low loss can be a challenge. A simple duplexer would employ a low pass filter from the radio to the 2 meter antenna and a high pass filter from the radio to the 70 centimeter antenna. If the filters have low insertion loss and the board layout is very clean, Wam! Jan 04, 2020 · At one meter, the rear lobe measured approximately 135mV. The front lobe at the same distance was 2100mV. The red arrow indicates the approximate center of the forward lobe and indicates less than bilateral symmetry. Based on using this antenna for radio direction finding, this is correct.

The DUT is my dipole antenna with a 20m 5D-2V coax cable. The dipole is not resonant at 40m band, because the whole length of the antenna is about 12.5 m. The measured values of CH1=2.093 V, CH2=892.2 mV, and CH2-delay=+25.0 nS give Zdut=2.961-j11.148 ohm. Considering the cable length of 20 m, Zant=215.987-j378.040 ohm.Zotac used warranty
