Is the Frequency Adjustable?

For FM Radio Transmitter, Power Below 2KW is all adjustable. For TV Transmitter, all Frequency Band is very Narrow, only can contain around 3 Channels, so it's not adjustable.

Is your Analog TV Transmitter can be upgraded to Digital?

Yes, we can. But the Frequency Band should be the same. After upgrade to Digital, the Power from TV Transmitter reduced 5 times.

How to do installation of these equipments?

For small power station, the equipments are very easy for installation. For large power station, we can send our engineer to your country to help you do the installation, but you should pay the cost.

How to operate these broadcasting equipments?

We provide All-English user manual and All-English operation software in our equipment. We also can do training for your engineer here in our company.

What about after sales?

The warranty time is one year after goods leaving factory. We can provide technical support from internet or in our company. We can send spare parts to you directly when the equipment damaged.

AI-Powered supplier vetting

SummaryZHC, legally identified as Hangzhou Zhongchuan Digital Equipment Co., Ltd., is a China-based manufacturer/factory in Hangzhou, Zhejiang, specializing in FM and TV wireless broadcasting equipment. Its stated capabilities cover R&D, production, marketing, engineering installation, and after-sales service. The supplier reports ISO 9001 and ISO 14001 management-system certifications, plus production-license and network-certification credentials for wireless transmission equipment. Production evidence includes three production lines and annual FM transmitter output of 2,000 pieces, while quality-control staffing is reported at fewer than five employees. ZHC exports to multiple global regions and has held self-operated import/export rights since 2008. Overseas service infrastructure, detailed innovation results, customization services, raw-material traceability, and customer cases are not sufficiently documented. The SGS audit record shown expired on 2024-11-08, so it does not establish current audit validity.

Supplier typeThe supplier is identified as a manufacturer/factory and a limited company, with its business categorized in manufacturing, although one record also labels it as a trading company. Its stated operations and product information support a manufacturing role, but the conflicting classification should be clarified during verification.

CertificationsZHC reports ISO 9001 and ISO 14001 certifications, as well as wireless transmission equipment production-license and FM Radio & TV equipment network-certification credentials. An SGS audit record exists, but its stated validity ended on 2024-11-08, so current audit status is not confirmed.

After-Sales capabilityThe company explicitly states that it provides engineering installation and after-sales service and describes service as customer-oriented. However, overseas warehouse, showroom, agent/branch, and offline trade-show capabilities are all marked unknown, leaving the scale and geographic coverage of after-sales support unverified.

R&D capabilityZHC states that it conducts R&D, emphasizes independent innovation, and has assembled technical and management personnel; R&D engineers reportedly have 11–20 years of total experience. Nevertheless, new-product launches and detailed R&D outcomes are unknown, so innovation strength cannot be fully assessed.

Production capacityThe supplier reports production of FM and TV transmission equipment, three production lines, and annual FM transmitter output of 2,000 pieces. Its production-license certification and stated manufacturing activities support an established production capability, although quality-control staffing is limited to fewer than five personnel.

Product Q&A

Q:What are these equipments used for?

They are professional used for FM Radio & TV Broadcasting Station (Transmitting equipment).

Q:What equipment & solution your company can provide?

We can do complete solution for FM Radio Station System including Studio, Link, Transmitter, Cables, and Antenna. We also provide the complete Transmitting part of TV Station.

Q:How large areas can One Station cover?

One FM or TV Station can cover one city or one town. The Maximum cover ranges of one station can not over 100KM Radius because the Earth is Curve.

Q:How do I choose suitable equipments for my station?

The most import factors are Power and Frequency. We need to know the Power and Frequency you need exactly, the distance you want to cover, and the height your Antenna can be installed.

Q:How to calculate Broadcasting equipment Cover Range?

The Cover Range depends on 4 factors: Power from Transmitter, Height of Antenna, Gain from Antenna, and Around Environment.
