(1). 1 TX to 1 RX: use 75-5 coax cable can transmit up to 500M or more (below 4CH channel);(2). 1TX to 1 RX (add amplifier): Transmit distance over 500M. The distance decided by amplifier, we suggest you use adjustable gain of the amplifier, and put it on the location of TX after 200M. (3). Splitter mode (1TX to 8RX): Use 75-5 coax cable can transmit over 500M, and can add many RX in theory.(4). Splitter mode +Loop out mode: The transmit distance will be different because each TV splitter has 3dB –5dB signal attenuation. We suggest you add one amplifier. (5). Matrix mode(6TX to 6RX): Use 75-5 coax cable can transmit over 500M. You can add many RX in theory. Due to the limitation conditions, we have not test. (6). Please check the right channel when you use. Transmit the signal for long distance, please use low channel; low distance, use high channel. As for details, please see the below. 400-500M————5-1CH 200-400M————20-5CH 100-200M————80-20CH Below 100M————we do not suggest
