[Avionics Today 08-31-2016] Indonesia’s Pratama Wahyu Teknik (PWT), a communications systems integrator headquartered near Jakarata, has contracted the ASC signal division of Communications and Power Industries (CPI) for High-Frequency (HF) air-to-ground communications and navigation antennas. PWT has ordered four Model 3005 Spira-Cone HF antennas for the Indonesian National Directorate General of Civil Aviation to function in the Regional and Domestic Air Route Area (RDARA) coverage agency in Makassar and Merauke, Indonesia.
CPI ASC Signal Division’s Model 3005 HF antenna system was first developed to meet a requirement by the U.S. Navy for a low-profile antenna to replace older, rotatable log-periodic antenna systems. This model includes mode-voting technology, which is widely used in non-commercial HF systems, and extends the use of that technology into the commercial sector.
"The Southern Pacific region [of Indonesia] relies heavily on air transportation for a variety of its social and economic needs, and it is vital that it has access to reliable, proven technology for aviation communications and navigation applications," said Keith Buckley, president of CPI ASC signal division.
