RFS thinking ahead at IBC08
Broadcast technology leader Radio Frequency Systems (RFS) will demonstrate the industry's most comprehensive portfolio of RF solutions designed to support the digitisation of television--including mobile TV--at the IBC 2008 exhibition in Amsterdam. Incorporating a suite of new antennas and filtering solutions, RFS's end-to-end solution-set is smaller, lighter, more affordable and higher performing than ever before.According to Mick Bennett, RFS Global Product Manager for Broadcast and Defence Systems, the company is investing significant resources in R&D, with a large number of new products recently released and many others in development. "The industry is at a pivotal point, with preparations for analogue TV switch-off, further digital deployments and, of course, planning for mobile TV," he said. "RFS's mission is to have solutions available to support all these activities when they eventuate. We're thinking ahead to what will be required and making sure we're addressing all the issues before they actually occur."
The result is the most comprehensive end-to-end broadcast RF solution-set on the market, comprising a full suite of antennas for DTV and mobile TV broadcasting, plus combiners, filters, transmission line, and switch-frames with digital monitoring options. "In addition to launching new products, we've focused on many existing products as well," said Bennett. "Every single building block is enhanced and our panel antennas are unarguably the best-performing on the market."
Central to RFS's IBC exhibit will be a suite of vertically polarised omni-directional mobile TV antennas, specially designed for co-location at mobile base stations. This will include two additions to the range: the fully broadband, lightweight MTV-4, and the CTV series of compact multi-channel antennas.
Weighing in at only 25kg, the 140mm diameter MTV-4 is the smallest antenna of its kind, accommodating input powers of up to 1kW and supporting frequencies from 470 to 806MHz. Complementing this, the four antennas in the 500W CTV series are suitable for multi-channel operation, and together cover the full range of UHF mobile TV frequencies. Both the CTV and MTV-4 antennas are ideal for deployment at mobile TV repeater stations, which will likely be co-located with existing infrastructure such as mobile base stations.
Also launched at IBC will be a series of sophisticated filtering solutions, specially designed to support co-location of mobile TV services at mobile base stations. These include two new low-pass filters--the 2kW LPF8E4 and 5kW LPFS16E4--that attenuate all frequencies above the UHF TV broadcast band up to 4.5GHz, including harmonics. Such filtering will be essential to prevent interference to co-located cellular services.
RFS will also launch a unique two-in-one mobile TV filtering solution that has never-before-seen levels of flexibility. The rack-mountable 6PX80E band-pass filter with integrated low-pass filter provides both DTV transmission mask and low-pass filtering in one unit.
Also on display at IBC will be the company's high-performing broadband UHF panels, further mobile TV antennas, RF combining and digital monitoring solutions, and semi-flexible HELIFLEX coaxial transmission line.
