Wireless monitoring relay - Cheap and analog wireless video repeater ST0104

Product description: ST0104 series is an economical analog repeater. Its power margin, small current consumption, under normal operating conditions about current 1.2A. And a small, well-crafted, transmission distance, suitable for all kinds of complex physical environment. Using 0dB (ie, wife small antenna) full-time-directional antenna, open area to ensure the transmission of about 1000m, if high-gain directional antenna, the distance can be increased to 3 km or more, under normal circumstances can also be transmitted to block 150-200 meters. This paragraph can be used for remote analog device relaying. A professional filtering technology, can effectively filter out unwanted interference signal space, so the normal reception signal is valid through increased noise immunity devices, the device according to the specific needs, choose a different capacity lithium battery for power. It is a highly cost-effective portable analog relay device. Model Description: The products are divided ST0104A and ST0104B models. ST0104A: Factory frequency of: receiving a 1080MHZ, launch of 1200MHz. ST0104B: Factory frequency of: receiving a 1200MHZ, launch of 1080MHz. Other bands needs to be customized in advance.
