Can different frequencies be broadcasted from the same antenna simultaneously?

Yes, different frequencies can be broadcasted from the same antenna simultaneously, a technique known as frequency division multiplexing (FDM). This allows multiple signals to be transmitted over the same medium without interference, as long as the frequencies are sufficiently spaced apart. However, careful design and filtering are required to avoid cross-talk and ensure signal integrity. Additionally, the antenna's bandwidth must accommodate the range of frequencies being transmitted.
