From the analog fishbone-antenna era to today’s DTMB digital HD broadcasts, Canwei Technology has always stood on the front line of terrestrial installation in Guangdong.
Canwei Technology is a professional team with 30+ years in DTMB antenna installation and research, headquartered in Shenzhen. We are not a shop that "sells whatever antenna" — we are specialists who have gone deep into terrestrial reception: from transmitter distribution, band characteristics and gain matching to rooftop wind-proofing and waterproof cabling standards, every step is backed by 30+ years of field experience.
As officially authorized agents for the three brands KBOX DTMB set-top boxes, Qiaohua DTMB antennas and ANTOP DTMB antennas, we insist on "survey first, then equipment selection, then installation" — never overselling expensive gear, never cutting tuning standards to save effort.
We started out installing analog fishbone antennas, running across rooftops in the towns and villages of Shenzhen and Dongguan, until we could "read the skyline and know where the tower is".
While cable swept into every home, we kept researching terrestrial broadcasting — tracking transmitter construction and band changes across Guangdong and building first-hand coverage data.
When the national DTMB standard landed, we upgraded our tuning techniques ahead of the curve: from "watching strength" to "measuring quality" — full-channel SNR re-testing became our acceptance standard.
We became official agents for KBOX set-top boxes and Qiaohua/ANTOP antennas, with a service network covering all 21 Guangdong cities — unified workmanship standards, unified after-sales, 5000+ homes and businesses served.
We track channel adjustments and signal changes everywhere and keep refining our installation craft — so every customer gets one install and years of stable viewing.
Whether an install will work is decided by field-strength meter data. If the survey fails, we tell you honestly — never install on wishful thinking.
Clamps tightened, seals waterproof, cabling tidy — the parts you can’t see deserve the most care, and typhoon season is the proof.
