NAB Sneak Peek: Dielectric Aims Low and High With Antenna

Powerlite DCR-T enters HD Radio and LPFM markets

Antenna-maker Dielectric says it has adapted its Powerlite DCR-T antenna for the special needs of HD Radio and LPFM broadcasters. The key, according to the company, is added control of directionality.

The circularly polarized DCR-T directional antenna is offered as a cost-effective solution for low-to-medium power FM and translator stations, which traditionally required a far more expensive antenna in designs typical of higher power operations, to meet directional pattern requirements.

Dielectric says this is possible because special software reduces antenna costs and production lead times, and with most FM translator directional antenna requirements, significantly reduces the price of the FCC proof of performance. The software that provides the proof of performance data required to confirm directional pattern compliance, as opposed to the traditional method of verifying patterns with physical scale models.

Dielectric Sales Manager Steven Moreen said, “The ring-style design of the DCR-T antenna, with its stable axial ratio independent of impedance tuning, is an ideal platform on which to add directional signal control. And, given the efficiency at which Dielectric can produce these antennas, the antenna can be delivered within weeks as opposed to months, along with the associated FCC proof of performance.”

The company adds that the DCR-T’s broadband capability offers enough bandwidth to accommodate HD Radio signals alongside analog FM, with in-field channel adjustments should channels change. The low-profile design offers less wind resistance. An optional radome is available.
