Spreading and Underground Antennas

The test was made in summer time 1999, when propagation was not too bad. Spreading and Beverage antennas were installed in a wild field near forest and were directed to the West. Spreading and Beverage Antennas had SWR no more the 2.0:1.0 on the tested bands 10- 160- m.

Conclusions

Spreading and Underground antennas still are waiting for amateurs with experiments. The antennas maybe installed at lots places where usual antennas cannot be installed.

The Spreading and Underground antennas may be almost invisible for bystander but the antennas allow operate in the Air.
