Installation Notes

Connect a suitable 3.3 GHz antenna before powering the transmitter; operating without an antenna risks damage.
Mount the unit securely and allow airflow around the cooling fan.
Use a receiver that supports the selected 3.3 GHz channel and analog video format. The VRX shown in some reference images is not established as part of this VTX SKU.

FAQ

How many channels does this 3.3G VTX provide?

It provides 16 listed channels: eight in Band A and eight in Band B, from 3170 to 3470 MHz.

What output power settings are available?

The listed settings are PIT, 25 mW, 200 mW, 1000 mW and 4000 mW.

Can a flight controller change the VTX settings?

Yes. Connect the VTX DATA pin and configure the flight controller for IRC Tramp. The onboard button and RGB indicator also provide local adjustment.

Can a 5.8 GHz-only receiver display this VTX signal?

No. The receiver must support the selected 3.3 GHz channel and analog video format; a 5.8 GHz-only receiver does not cover this transmitter's listed channels.

Can the transmitter be powered without an antenna?

No. The supplied technical sheet warns that the antenna must be connected before use to avoid possible damage.

B2B Procurement FAQ

Is the 3.3 GHz VRX included with this VTX?

The supplied SKU image identifies the 3.3G 4W VTX, while other images also show a VRX. The images do not establish a combined packing list. Request a confirmed bill of materials if a transmitter-and-receiver set is required.

What information should be provided for a quotation?

Specify the required quantity, 3.3G 4W VTX configuration, antenna requirements, whether a matching receiver is needed, and the delivery destination. Final contents and commercial terms should be confirmed in the quotation.

Are alternative channel plans available?

The documented standard unit uses Bands A and B. Any alternative frequency plan must be reviewed and confirmed against the required configuration before an order is placed.

What are the MOQ and lead time?

MOQ, availability and lead time are not established by the supplied product material and must be confirmed during quotation.
