Which of the following can reduce overload of a VHF transceiver by a nearby commercial FM station?

Receiver overload occurs when a very strong nearby signal, such as a commercial FM broadcast station, overwhelms the front-end circuitry of your receiver. To fix this, you must block the specific frequencies of the interfering station while allowing your desired VHF frequencies to pass through to the receiver. A band-reject filter (also known as a notch filter) is specifically designed to attenuate a narrow band of frequencies while passing others. Conversely, installing an RF preamplifier would actually make the overload much worse by amplifying the already overpowering interference. Double-shielded coax and bypass capacitors do not fix strong signals entering directly through the antenna.
