Having antenna problems? How do you know if you need a new antenna? It's sometimes hard to tell with FM, because relatively strong FM signals can sometimes be picked up without an antenna. On the other hand, if you get nothing across the entire AM band, you probably need a new antenna.

If you can tune in a station, gently take hold of the antenna near its base and jiggle it lightly back and forth. If the signal pops in and out, your antenna is not making firm contact with the body of the car. It may just need tightening, or it may be partially corroded and need replacing.

Stock antennas may need to be replaced after only four to six years. They wear out faster if you live near the ocean, where the salty sea breezes can accelerate corrosion. We recommend replacing the antenna only when the mast is obviously rusted or broken. However, if you have an antenna that's embedded in the windshield, you'll get better reception if you upgrade to a fender-mounted antenna.

If you want the convenience and security of a motorized antenna, which automatically raises and lowers the mast, we have models to fit most vehicles. However, a motorized model won't improve reception unless the original antenna has gone bad.

You might need a cable adapter

Some GM, VW, and Nissan vehicles require an antenna cable adapter to accommodate an aftermarket antenna. Crutchfield stocks these adapters and our expert Advisors will be sure to let you know if you need one when you place your order.

In most cases, you need to remove your radio to reach the antenna plug. If you buy your antenna from Crutchfield, you'll get the receiver removal instructions for your vehicle for free. As with anything else you buy from us, we'll be here if you need any help when you install your new antenna. Our Technical Support staff is just a phone call away.

    Hi, I am in need of an antenna mast for my 1989 Lincoln Town car. The car has a newer Pioneer radio. I am in need of an antenna mast to replace the broken one for my car. The over all length of the antenna mast and stainless steel shaft (whip) was 54 inches. I can provide the length of the stainless steel upper section of the mast at a later time. The mast currently is the 3 piece sectional type but the car originally had the four sectional type. The closed section, from motor to upper wheel well, I believe is 8 to 10 inches in size, I can confirm this at a later time. Do you have antenna masts that might work for my car? This car is a good condition, summer car. Thanks Stephen

    Stephen, we carry this replacement antenna for a 1989 Lincoln Town Car with a toggle-style volume control on the factory stereo. A Crutchfield MasterSheet is included with your purchase to help you install it. However, please note that if your Town Car's factory stereo has a rotary volume knob, we do not carry a compatible replacement antenna. If you have any questions, don't hesitate to give us a call, and for an in-depth look at the recommended antenna, click the "Details" tab on the product page and download the owner's manual.
