Abstract

For empirical research on Near Vertical Incidence
Skywave (NVIS) characteristic wave propagation, a beacon transmitter system is needed that can be programmed to emit precisely defined elliptically and circularly polarized waves at high elevation angles. This paper proposes a novel hybrid antenna-transmitter system, a combination of a synchronous dual channel transmitter and a turnstile antenna. The polarization emitted by the turnstile antenna is defined by the power ratio and phase difference of the outputs of the
transmitter. Operating frequency is between 3 to 10 MHz. An automated and transportable solution is described, which can be fed by battery or solar power. Power consumption is 5.7 W.
