If all channels are missing, it's the collective antenna or your TV. If one to two, it's the antenna. You can only check if your antenna is in good working order and you have another TV, or you can check your TV. If you check as described by Mikhail Fedorovich, it is impossible to say obviously that the antenna is faulty. If the HF unit is faulty, the TV can show normally on the LF input, but the antenna will not show?

You should have vacuumed it more often. Blow it out.

Set the TV to video input mode and input the signal from a VCR or DVD player. If the picture and sound are normal, it is most likely the antenna. Check if the antenna plug is securely plugged into the TV socket. If it is, check the antenna cable to see if it is damaged. More often the central core is broken in the antenna plug, so it is possible that there is a contact - the TV shows, then it is not - the TV does not show. As a last resort you can connect a room antenna to check the TV if you use a collective antenna.
