Does the Stubby Antenna affect signal strength?

Yes, a stubby antenna can affect your signal strength. A stubby antenna is not a high performance antenna. Your proximity to the signal source along with terrain can influence the reception strength. If AM/FM reception is important to you, stubby antennas should be used in areas of high signal strength. It is recommended for use if you have a strong signal with the stock antenna or simply don’t use your AM/FM radio. Returns accepted without question if the antenna doesn’t meet your expectations.
