How can I watch cable TV without a set-top box in the hotel?

There are usually two ways to do this.

First, digital-to-analog conversion. The digital audio and video output by the set-top box is converted into radio frequency signals by radio frequency, and then mixed and sent to each room. The room TV directly receives analog signals without additional equipment. The current coaxial cable can be reused on the line. Low cost. However, due to the conversion to analog signals, the line noise will be more obvious, resulting in the terminal effect is not as good as the direct set-top box, which is prone to snowflake noise. This method generally requires a set-top box for each channel, and it is meaningless if the channel to be transferred exceeds or is close to the number of rooms.

Second, the digital signal is converted into a network signal for transmission. This is suitable for free channels. The signals are packaged and sent to the local area network through special equipment, and are received and decoded by the network set-top boxes in each room. Few front-end devices are needed, and only one device is needed for each frequency point. If customized, a device can correspond to up to four frequency points. However, every room needs a set-top box, and the total cost is not low.

Either way, you must get permission from the local radio and television department, otherwise it is illegal.
