RFS (Radio Frequency Systems), the wireless infrastructure specialist, is unveiling its innovative UHF broadband MTV-4 antenna to the mobile industry in Barcelona. The MTV-4 is the latest addition to RFS’ comprehensive range of mobile TV antennas which includes the compact CTV series with 6dB gain; the ultra-slim ultra light-weight HU6 range of systems; and the
SDV-4 wide frequency omni-directional unit.
Mobile TV technology is exciting broadcasters and carriers around the world, but standards vary between regions and even countries within regions. RFS can help carriers generate valuable extra revenue streams from this still-evolving technology.
The RFS range now includes solutions that are visually unobtrusive and ultra-lightweight to meet the latest environmental and structural considerations and they are all flexible on both frequency and standards
According to Mick Bennett, RFS’ global product manager for Broadcast and Defense Systems, a wide range of cost and performance option solutions are needed to support global deployments of what will increasingly become a revenue and ARPU-enhancing technology. “RFS already has,” he says, “solutions for most countries, standards and applications.”
To meet the requirements of co-located cell-based wireless and mobile TV solutions, the RFS mobile TV antenna suite features a range of power and bandwidth options. Low-power options are essential to ensure that emissions remain within limits and co-sited cellular receivers are not blocked. RFS mobile TV antennas range from single channel, through multi-channel to full-band.
MTV-4: only 20kg with support for the complete UHF TV band
“Central to our strategy of enabling carriers in their rollout of mobile TV services is a range of lightweight antennas that now includes our new MTV-4, a lightweight antenna system which supports the entire UHF TV band,” Bennett said.
He went on to say that, at only 20kg, the 140mm diameter MTV-4 is the smallest broadband antenna of its genre.
Electrically, physically and in terms of cost-effectiveness, he said, the MTV-4 stands alone in its class and, by accommodating input powers of up to 1kW with a gain of 6dB, the MTV-4 is fully UHF mobile TV broadband compliant. This is made possible by the use of a single antenna supporting frequencies from 470 to 860MHz.
This combination of power and bandwidth makes it ideal for supporting multi-channel mobile TV operation. Moreover, says RFS, the unit’s small size and low drag profile provide a high wind speed rating and low wind load characteristics.
CTV: compact, 500W input and 6dB gain
The compact CTV series features center-fed co-linear antennas, with an impressive 500W input power rating and 6dB of signal gain.
The four antennas in the CTV series are, says Bennett, very suitable for multi-channel operation, and together support the full range of UHF mobile TV frequencies from 470 to 860MHz.
“The four antennas in the 500W CTV series cover the full range of UHF mobile TV frequencies. Both our CTV and MTV-4 antennas are ideal for deployment at mobile TV repeater stations, which are likely to be co-located with existing infrastructures such as mobile base stations,” he said.
“A central requirement for this is sufficient signal strength to provide good reception, balanced against power limits to avoid blocking co-sited cellular receivers. Just as important are antennas that are visually unobtrusive and ultra-lightweight to meet environmental and structural considerations,” he added.
HU6: ultra slim and compactness the order of the day
Weighing in at just 3.5Kg, the ultra-slim HU6 is one of the world's most compact UHF omni-directional antennas. For single-channel networks, the HU6 offers an 8MHz channel and accommodates input powers of up to 300W.
“The HU6 is an excellent choice for single-channel networks,” said Bennett, adding that the technology has proven itself to be useful in a number of situations ever since the first trials of the antenna in Oxford, UK, back in 2005.
The UK DVB-H trial, says Bennett, was set up around the city of Oxford to investigate the commercial appeal of mobile TV and to see how the technology performed.
“At the time we supplied a low visual impact HU6 co-linear antenna for deployment at a low-power urban site. The trial, which broadcast on UHF channel E31, involved eight transmission sites and was a great success. Since then, the HU6 has proven itself to be a great addition to our range of mobile TV antenna,” he said.
SDV-4: omni-directional, 1kW input
The SDV-4, meanwhile, is a vertically polarized, omni-directional broadband antenna that supports the entire mobile TV UHF frequency range (470 to 800MHz), offers premium VSWR (voltage standing wave ratio) performance and accepts up to 1kW input power.
“Weighing 45kg, the SDV-4 series offers an extremely high-performance, cost-effective and low-power solution for deploying mobile TV services
co-located at multiple base stations,” said Bennett, adding that a higher gain/high power 2kW version of the antenna is also available.
All of these innovative products, says RFS’ global product manager for Broadcast and Defense Systems, can be deployed in a very wide range of countries.
“Perhaps more importantly though, as standards evolve and countries agree on which of the standards they will support, the antennas and associated cabling - as well as their electronics - can be modified to meet the new standards and requirements as they evolve, with minimal modifications being required,” he said.
“It’s this high degree of flexibility, allied to the quality that RFS antenna products are renowned for around the world, that we are extremely proud of. We welcome carriers visiting our stand/booth at the GSMA World Congress event to discuss the latest in mobile TV antenna innovations that RFS can offer. ” he added.
