The Table 1 shows that at all amateur HF Bands my
Beverage Antenna has the gain much below zero. However it is possible
compensate at receiving mode by turn on the internal transceiver's
preamplifier. At transmitting mode only propagation may help me.
However I often received reports 559- 579 at 160- 20 Meter Bands
where the antenna losses are big enough. At the 17- 10 Meter Bands
the report 599 is common one there. It is very interesting that
practically measured SWR is close to the theoretical one above
the 160- Meter Band where the some known inaccuracy in simulation
is happened. Figure 2 shows SWR of the Beverage Antenna measured
with the Rig Expert AA1000. It is very close to the reading by
the IC- 718 and to the theoretical calculated by the NEC for MMANA.

Another important side of the Beverage Antenna is the
Diagram Directivity. Below Figure 3 to Figure 11 show DD of the Beverage
Antenna at the 160, 80, 40, 30, 20, 17, 15, 12 and 10- meter Bands
in the vertical plane. Feedline with matching transformer is on
the left side and the termination resistor is on the right side
of the figures. As you can see from the Figure
3 - Figure 11 the DD of the Beverage Antenna is far away from a
perfect one. Antenna has signification radiation into zenith.
It is may be not bad for 160- 40 Meter Bands where it gives local
QSOs. However at the higher bands it is just waist of the transmitter
power.
