A recent study was conducted for Radio Pulpit by Broadcom International and Sentech Ltd., involving a Kinstar antenna installed by Communications Technology Broadcast Ltd. in South Africa that was fed by an Ampegon 10 kW DRM30 transmitter operating on 1440 kHz. The results of the field measurements reveal that the wide bandwidth, high-efficiency characteristics of the Kinstar antenna set it apart from any other low-profile AM/MW antenna in the world. This was demonstrated in the data showing an average radius for omnidirectional coverage of 68 km (from the transmitter site) for 64QAM modulation and 78 km for 16QAM. The 16QAM skywave coverage extended out to a range of 210 km from the transmitter site.
These results demonstrate the true qualities of the Kinstar antenna design over and above the fact that it requires no paint, no lights, and has low-vulnerability to lightning. The Kinstar antenna is a proven technology that is ready for prime time in the world broadcast market.
