I received an order to perform frequency blocking for 50 rooms, each room measuring 20-25 square meters. The device will be hidden inside a vase with artificial flowers. These are the frequency ranges I would like to block. What is the effective power output for a room of this size? Can you customize it to these frequencies? How many antennas will the final device have? In the first stage, I will place one order to make sure everything works as planned, and then I will move forward with the rest of the quantity.
