They're useless.

some radios need to have antenas that are specific lengths which are different from stock

All radios need the same length antenna. The length of the antenna is based on the frequency of the transmitted signal, something that is obviously not determined by the radio. The standard antenna length is 31" to 33", which represents 1/4 of the average wavelength from 88.1mhz to 108mhz. Antennas need to be in fractional increments of the wavelength to cause the proper resonance, so your average antennas will be 1/2, 1/4 (car antenna), 1/8 (cell phone), etc. Wavelength=C/F where C is the speed of light (3x10^8m/s). Therefore, for a 100mhz frequency, you have (3x10^8)/(100x10^6)=3.0 meters=118.1 inches. (118.1in)/4= 29.5inches, which conveniently enough, is the approximate length of your antenna.

hehe. No. I'm an electrical engineer who chose my major because of my love for audio, so I've been able to apply what I've learned to the audio field.

Jim85IROC,

Are you into home audio and the whole tweeky world of the audiophile--sand/lead shot, spikes, cables, coupling and decoupling, SACD and DVD-A, and oh, hell, you get the picture.

I'm an audiophile, not a nutcase. Any idiot that thinks his $5,000 speaker wire sounds better than my $4,000 speaker wire is nuts

I don't perscribe to that esoteric crap, but I do have about the best system I can afford right now. Unfortunately it's all at home stuffed into my bedroom, and out here at school I've got a cheap JVC receiver and 2 small Sony speakers. Hauling stuff back and forth in a Camaro isn't fun, so I travel bare-bones when at school.

Jim85IROC,

For me, audiophiles and car freaks have much in common with tweeks=--me included. I've spend a fortune on both.

Remember, that 31" antenna length is only a "best compromise." You'd actually want a slightly different antenna length depending on what station you're listening to, from 88.1 to 107.9 megaHertz. My sister's factory Lexus system actually slightly raises and lowers the power antenna as you tune to different stations.

Those FM boosters are almost entirely useless. Remember that they "boost" everything, including the static. And also remember that you can't create a radio signal that doesn't exist. Usually, the FM booster just overloads your tuner and causes it to sound like crap.

The only time a booster might be of some use would be if you had one of those $20 Kraco radios; it might do a little something I suppose.

As another example, my three-storey house has 9 cable TV outlets. The cable company installed a signal booster, but its purpose is to compensate for the losses incurred in the signal splitters, as well as the long cable runs.

I suppose if you had a car radio in your basement, and a 100-foot cable going to an antenna on your roof, it might be worth trying one of those boosters there as well.
