Do I need an amplifier for this antenna?

Not necessarily. An amplifier is not automatically required simply because the antenna is used outdoors. Whether an amplifier is useful depends on local signal strength, cable length, signal distribution requirements and the number of TVs connected to the system.

AI-Powered supplier vetting

SummaryZHENGZHOU LEHENG ELECTRONIC TECHNOLOGY CO., LIMITED is identified as both a trading company and manufacturer/factory in China, offering antennas and related communication products. It reports nine production lines, multiple antenna product outputs, broad export coverage, and ISO9001:2015 certification. The supplier supports several forms of customization and accepts OEM orders, but the evidence does not establish 3D software design, ODM, SDK, or recent product-development capability. Service-control documentation is incomplete: procedures exist for some activities without records, while complaint handling lacks written procedures and records. The supplier reports no inventory, overseas warehouse, or overseas showroom capability. No customer cases are explicitly documented. Financial evidence is insufficient for assessment.

Supplier typeThe supplier is legally structured as a limited company and is described as both a trading company and manufacturer/factory. Its stated business scope includes communication equipment and antennas, while another record identifies it as a trading company, indicating a mixed trading and manufacturing profile.

CertificationsThe company description states that the supplier passed QMS ISO9001:2015. A TUV Rheinland audit record is also listed with a validity period from 2025-12-30 to 2026-12-29, but the audit result is recorded as “0” without an explanatory interpretation.

After-Sales capabilityThe supplier claims superior pre-sales, in-sales, and after-sales service, but its documented service controls are weak: complaint handling has no written procedures or records, and corrective-action procedures have no written records. It also reports no in-stock service, overseas warehouse, or overseas showroom capability.

Production capacityThe supplier reports nine production lines and detailed output across 5G, 3G/4G, GPS/GLONASS antennas, and antenna parts, supporting substantial production capability. However, its outsourcing procedures and contracts are unknown, and it reports no inventory service capability.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, and its company description states that OEM is accepted. These records directly support broad customization capability, although they do not establish 3D software design services.

Product Q&A

Q:Why would a buyer choose a VHF/UHF antenna instead of a UHF-only antenna?

A VHF/UHF model can receive television channels distributed across both frequency ranges, so buyers do not need to select an antenna based only on UHF coverage. This is particularly useful in markets where terrestrial TV services use both VHF and UHF channels.

Q:Does a directional antenna need to face the TV transmitter?

Yes. Because this is a directional antenna, installation orientation matters. For best reception, the antenna should generally be aimed toward the relevant broadcast transmitter or signal source.

Q:Is the advertised 70-mile reception distance guaranteed?

No. The 70-mile figure should be regarded as a specified reception distance rather than a guaranteed result in every installation. Actual reception depends on transmitter power, terrain, buildings, antenna height, cable loss, local interference and other environmental conditions.

Q:Why can the same antenna have different gain on VHF and UHF?

VHF and UHF are different frequency ranges, and antenna performance varies across frequency. This model is designed with separate performance characteristics for the two bands, providing 4-8 dBi gain on VHF and 11-17 dBi on UHF.

Q:Can this antenna be used in areas with multiple TV transmitters?

It can be used where the desired broadcast signals can be received effectively from the installation direction. Since the antenna is directional, buyers should evaluate the relative locations of local transmitters before selecting the installation direction.
