FAQ

Q1. Is the Frequency Adjustable?

A1. FM Radio Band Frequency is 87~108MHz, TV Band Frequency includes UHF/VHF band.

For FM Radio Transmitter; Power Below 2KW is all adjustable. Above 2KW would be narrow.

For TV Transmitter; all Frequency Band is very Narrow, only can contain around 3 Channels; so it’s not adjustable.

Q2. Is your Analog TV Transmitter can be upgraded to Digital?

A2. Yes, we can. But the Frequency Band should be the same.

The only difference between Analog & Digital TV Transmitter is its TV Modulator.

After upgrade to Digital, the Power from TV Transmitter reduced 5 times.

For example: 1KW analog TV Transmitter can be upgraded to 200W Digital TV Transmitter.

Q3: What is the Warranty for our tv box?

A3: All products have 1 year warranty. If there is no man-made problem, we will replace or repair for you freely. we own the best quality control department and professional sales team, if any problem happen,our team wil do our best to solve for customers.

Q4: Can you provide EU or US, UK, AU or others standard plug power adapter?

A4: Yes, there is EU, UK, US, AU etc. standards of plugs are available. The adapter we send to you is accordingly to your country standard or your request.

Q5: How long will my order received?

A5: DHL/UPS/FedEx Express usually takes about 3-5 working days to the destination. And it's about 5-8 working days by EMS or TNT. Hongkong Post Air Mail and Singapore Post Air Parcel take 10 to 30 days to ship to worldwide.
