This is a transmitter (TX) and receiver (RX) set for the Accsoon CineView Quad. The two main units shown in the photos, 8 antennas, and mounting parts are all that are included. Cables, AC adapters, and the original box are not included. I purchased this as a spare for professional use, and it has been used sparingly. In a simple operational check, both transmission and reception linked without issue, but as it is a used item, there are minor scratches and signs of use. Please check the photos for the condition. - 4-antenna dual-band wireless transmission system - TX/RX pair sale (not sold separately) - Stored in a smoke-free environment - No returns or refunds except for initial defects.
