Antenna Parameters: So, the antenna has been installed. After that
I have measured the antenna parameters. Figure
5 shows the schematic for the measurements. I test
the antenna with antenna analyzer MFJ 259B and usual SWR meter
HANDIC that was turn on in series with the transceiver IC-7410.
Before the measurement, both devices, MFJ- 259B and SWR Meter
HANDIC with SWR meter of the IC-7410 transceiver were verified
with loads 25, 50, 75 and 100- Ohm.

However, real data for the Beverage Antenna were
a little different with SWR meter of the MFJ-259B and the usual
SWR meter. For measurement with the HANDIC and IC- 7410 I used
80-W at 160 and 80 meter Band and 50-W at others bands.

Table
1 shows parameters of the antenna with termination load
of 460 ohms. Table
2 shows the parameters of the antenna with termination
load of 415 ohms. Table 3 shows the parameters of the antenna with termination load of 370 ohms.
Antenna with termination load of 460 Ohm had the best parameters
so I decided use to the load for my antenna.

I did not simulate the antenna
parameters in my lovely MMANA because of lots of ambient (that
I cannot simulated in the soft) may influence
to the antenna.
