do cable antennas work

Sometimes, in order to save money or be limited by the antenna field, it is necessary to share an antenna with two (or more) transmitters. At this time, the feeder from each transmitter shall be connected with a filter before receiving the common antenna, so that the electromagnetic energy flow of the unit will pass smoothly, while the electromagnetic energy flow of other transmitters will not. Backflow. Enter this machine. When designing a filter, it is necessary to ensure that all transmitters are matched with the antenna at work.

The same receiving antenna can also be shared by two (or more) receivers. The wave received by the antenna is then connected to each receiver via a wideband amplifier and a shunt coupling device (called an antenna sharing device).

In addition, several transmitters (or receivers) may also be connected to several different antennas on the switch via a change-over switch. The requirements of these switches are simple, easy to operate and small to reflect.
