Does a shorty Antenna hurt my reception?

The antenna on the car as it comes from the manufacturer is designed with a specific length in mind. The FM radio band runs from about 88MHz to 108MHz, with a centre frequency of about 98MHz. The wavelength of these signals is about 120.5-inches and the optimal length of a whip antenna for that frequency is a quarter wavelength or about 30 inches.

If you move the length of the antenna away from this ideal it's effectiveness will decrease. For strong signals like local, in-town radio stations you might not notice too much of a difference but you ability to pull in stations while on the highway will definitely drop, especially with an 8-inch part.

What he said.



I have an 8" antenna, but carry my stocker in my trunk. I have Satellite radio and NEVER listen to AM/FM anymore so the stubby is more for appearance.
