|Hong Da Industrial (HK) Ltd's double TV antennas for small television sets facilitate reception without recourse to roof-mounted models|
For the ordinary layman, the exact function of many electronic components is shrouded in mystery. On the other hand, everybody seems to know what an antenna does. Highly visible, it soon becomes clear that attaching an antenna results in greatly improved reception - and Hong Kong manufacturers offer a broad range.
One of the most obvious applications for antennas is in radios and television receivers, an area that Hong Da Industrial (HK) Ltd primarily addresses with its products.
"We manufacture antennas, mainly for customers in Europe, Australia and the Americas, at factories in Dongguan and Zhejiang Province on the Chinese mainland that employ about 900 workers," says manager Tung Man Lung.
Its double TV antenna is a particularly successful product, coming in the form of a compact, detachable, telescopic unit designed for small television sets to facilitate reception without recourse to a roof-mounted model.
In addition to antennas, Hong Da manufactures a wide range of electronic parts and components including speakers, microphones, capacitors, transducers and LEDs.
Mobile communications systems, of course, are highly dependent on good quality antennas to function properly. One company specialising in manufacturing models suitable for use with mobile and cordless telephones and walkie-talkies is Hong Kong Kechenda Electronic Co Ltd.
The firm supplies antennas to several household name brands. "We aim to manufacture reliable products for multinational companies. In order to be cost-effective and time-efficient, we have equipped a complete production system from tooling design and product manufacture to assembly," states sales officer Ronnie Hung.
Kechenda has developed 900MHz antennas for Panasonic and GM as well as 2.4GHz antennas for GM, he claims. Kechenda accepts minimum orders of 2,000 pieces, and can generally deliver within 10-20 days.
The ISO 9001-certified company, which employs 455 people at its 5,000-square-metre factory in Dongguan on the mainland, also makes a range of jacks, switches and connectors.
Manufacturing an extensive range of outdoor and indoor TV antennas at a 600-worker, 30,000-square-metre factory at Foshan on the mainland is Hong Kong Zhong Yuan Industrial Co.
"We are a subsidiary of Foshan Zhongyuan Creative Industrial Co Ltd, one of the biggest manufacturers of antennas and antenna accessories on the mainland," says president Vincent Cheung. "We have more than 28 years' experience in designing and manufacturing antennas, mostly under the Greentek and Redbox brand names. In addition, we do OEM work for well-known brands."
The company, which also manufactures boosters, amplifiers and directional couplers, offers a range of antennas that includes remote-controlled, rotating outdoor models; fishbone outdoor types; super-active outdoor antennas with optional rotators for far-ranging TV and FM radio reception; and indoor antennas with built-in, high-gain boosters.
Hong Kong Zhong Yuan accepts orders for a minimum of 2,000 pieces per model and delivers within 45 days of order confirmation. Major markets are Europe, Asia and the Americas.
Another firm, Kenbotong Communication Ltd, offers a range of antennas operating from 150MHz to 5.8GHz. "Antennas in the 2.4GHz range are popular," says managing director Jian Qiu, "and our models come in several formats: for indoor ceiling or wall mounting, for mobiles or fibreglass omni-antennas."
The company, which has been in business since 1985, displays a similar flexibility in customer service, with no minimum order requirement and prompt despatch of goods (FOB Hong Kong) within three days of confirmation. "We can offer OEM terms or our own KBT brand," says Qiu.
An OEM/ODM supplier of a diverse range of electronic components, Liberal Industrial Ltd offers duplexers, receivers, buzzers, filters and resonators. The firm also manufactures a range of antennas, including a GPS model. Other units are used for various applications including mobile telecommunications and wireless networking.
"Our major markets are Brazil, the US, Hong Kong and the mainland," says export executive Bonnie Yip. "We accept orders for 1,000 units and up, and delivery usually takes place 14-21 days after order confirmation. FOB Hong Kong unit prices range from about US$0.10-0.75."
Yip points out that the company's two factories - in Zhejiang Province and Huizhou on the mainland - are ISO 9002-certified and that the company has a comprehensive quality assurance system.
Another Hong Kong antenna maker is Union Team Ltd, founded in 1987. Set up originally to produce loudspeakers, the firm subsequently added antennas, microphones, transducers and other sound-related parts and components.
Today, Union Team Ltd operates three ISO 9001-certified factories on the Chinese mainland, which produce components used in-house and by manufacturers ranging from the toys sector to the telecommunications industry. Union also supplies these parts on an OEM/ODM basis.
"In addition to loudspeakers, essentially we are a one-stop electronic parts and components solution for many manufacturers," says marketing officer Jenny Lam. "We also tailor-make some components to specific client requirements, and we have a solid reputation for reliability."
Demonstrating that, whatever your antenna needs, it is a safe bet that a Hong Kong company will be able to offer an appropriate model at a competitive price.
