1.3GHz A/V Transmitter, 300mW (1258MHz Compatible)

1.3GHz A/V Transmitter, 300mW (1258MHz Compatible)

Don't let the small size of the Racewood 1258MHz / 1280MHz wireless A/V transmitter fool you. It offers excellent range with its 300mW (milliwatt) RF output. It's ideal for ham radio ATV, FPV, and other hobby wireless video applications.

A variety of antenna options are available so that can choose the antenna solution that is best for your application. The standard antenna is a monopole whip (suitable for non-critical short range applications). For those that need higher performance (such as FPV and sUAS applications) the antenna can be upgraded to our popular #ANTHWD-1200 or  #ANTVD-1300 dipoles at additional cost. Be sure to review their specs (by clicking the links) and then choose the one that is best for your application.


NOTE: Price varies depending on the antenna that is selected in the product options (see further below).



The TX1258-300 is in-house tested and calibrated. That's right, we go the extra mile for you; Every transmitter is validated on a HP/Agilent spectrum analyzer before we allow it to ship to our customers. RF power, video level, and the audio subcarrier accuracy is verified. These extra steps ensure your transmitter provides the best performance and reliability.

The power source is not included. It must be 12VDC (9.9V-12.5V allowed). Exceeding this voltage, or reversing the power connections, WILL cause permanent damage and void the warranty. AC-mains powered applications must use a voltage regulated power supply. For portable use we recommend a 3-cell (11.1V) lithium polymer LiPO pack such as our #LB3CR-610 with a #CORD-JB2 cable.

Important notes: The DC input connector is a 2.1mm barrel style connector that is center (+) positive. Reversed voltages will cause serious damage. NEVER operate the transmitter without an antenna or it may be damaged. Failure to follow these warnings will void the warranty. Please see the instruction manual for more information.
 

Notice: Due to its high RF power, using the TX1258-300 in the USA and other countries will require an amateur/ham radio license (some countries may forbid its use). It is your responsibility to ensure that its use meets the requirements imposed by your government’s RF spectrum regulations. Do not purchase this product if you are unsure of the government requirements or are not able to comply with them.
