Of course after I have found the theoretical data for my Beverage Antenna I would like to improve the antenna efficiency. Most simple way to improve the efficiency of a broadband Beverage Antenna is to connect to the termination hot end an additional wire with length that is not resonant for the used bands. To find the needed length and possible practical configuration is a not simple task. But I decided to do it. Additional wire in 7 meter length was connected to the antenna load. Figure 12 shows the antenna. Parameters of the antenna were simulated with NEC for MMANA. Table 2 shows the data for my antenna. Maxima gain is given to the radiation angle at where it is.
