Beverage Antenna. Theoretical Look on Practical Result.

By: Igor Grigorov, VA3ZNW

My Beverage Antenna (Figure 1, that was described at: http://www.antentop.org/019/va3znw_019.htm ) is successfully working at my station. The antenna was successfully tested at CQ WW 160- Meter Contest (CW), CQ WPX (2016, CW) and ARRL International CW Contest (2016). I worked there with my IC- 718 using only 50… 90- Wt.

However it stands interesting for me what is the theoretical data for my Beverage Antenna. Parameters of the antenna were simulated with NEC for MMANA. Table 1 shows the data for my antenna. Maxima gain is given to the radiation angle at where it is.
