Two Wires Beverage Antenna

450 Ohm load made from 10 each Resistor in  4k7

 

 

Table 1 shows SWR of the Two Wires Beverage Antenna. Measurement made by SWR meter JANA HJ 8017A, RF power going to antenna was 100 W. The SWR meter was tested by me with several loads (25, 50, 75 and 100- Ohms) and shows best data compare to others ones SWR devices that I have. The SWR meter was connected between transmitter and coaxial cable going to the Beverage Antenna. I also did measurement of the SWR of the antenna with help of antenna analyzer MFJ- 259B. The device helped me to tune the antenna but final SWR was measured with help OF usual SWR meter.

MFJ showed different data in different time of the day because the device analyzed both signals going to the antenna from the MFJ device for measurement and stray RF received by the antenna (that signals have different level in on the day that depends on the propagation of the radio waves). Figure 12 shows SWR meter JANA HJ 8017A.
