Folded Beverage Antenna 

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.

Figure 5 Schematic for the measurements of the Antenna Parameters

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.
