It costs you nothing extra, and it has not changed what this article says — where a competitor is the better answer, we say so. The antenna pair on each box makes this SVBONY kit look different from the little USB-sized video transmitters I have handled. I take out the transmitter and receiver and work through where the video and power connections go. The title calls it TransAir3, while my opening readout also mentions ST4 Transmaster. I am following the kit shown in this unboxing, without merging those names into a new model specification. ## The input and output arrangement I show the transmitter's input and local output connection, then the two HDMI outputs on the receiving side. I also point out the power controls and infrared connections. That explains the intended layout. It is not a demonstration of a working signal on three screens. ## A fairly complete accessories box I unpack HDMI and USB-C leads, infrared accessories, the small HDMI adapters and four antennas. I fit the antennas to the boxes and look at the mounting arrangements. For the audio side of a separate recording setup, my [SVBONY D4 microphone walkthrough]() covers a different kit. I am not testing the two products together here. ## The range test is explicitly next I finish by discussing a future connection and distance test. The minimum latency and open-space range figures I read are advertised claims, not measurements completed in this session. I do not verify app monitoring, multiple receivers, interference resistance or a particular display mode here. SVBONY supplied the kit; this first result is the hardware layout and accessories, ready for the later transmission tests I propose. ## Links from the video **Affiliate disclosure:** These links may earn me a commission at no extra cost to you. - [SVBONY TransAir3 original product/referral link]() - [MikeTheTech original Patreon link]() - [Geeksoutfit original clothing-store link]() **Coupon code: COLLAB1** — Discount amount not stated.
