Question: Is the little bit of bare wire on the non-plug end there for any reason?
Document: Very poor performance - antenna received a signal only when I was holding the bare wire at the end, and only in certain orientations. Save your money and buy some sort of amplified antenna such as a window-mount, or an external mast if you can mount it. Not worth the price.
I plugged it right into the antennae input on my boat stereo receiver and it works great. It even pick up very distant radio stations although they have a little bit of cyclic fuzz. Closer local stations within 30 miles are crystal clear no problem.
I bought it cuz it was cheap and needed it for testing things on my bench. I guess I could have made one, but was in a lazy mood and figured I would just buy it.Poor performance. It contains no ground plane.If you tack a wire a few feet long to the shield at the end and drape it down towards the ground it works infinity better.
antenna is a little short. I thought it was longer than this...its needs to be about 2 feet longer but at this price it cant be beat.
This antenna works great on my boat's stereo. Good range and no need to extend it, just plug it and enjoy the radio stations.
I got this little antenna for a camper I built and was so amazed It gets every station that my truck does with a regular solid antenna and you can hide it anywhere
My Jeep's antenna was roached, I plugged this into the back of my aftermarket stereo and fed the end behind the glove box. Picks up stations perfectly! This area gets horrible reception to my favorite stations but this picks them up better than my in-home stereo's.
supper easy to install, just plug it in, and secure it anywhere on the inside of your center council or anywhere you're installing it. No high profile antennas outside, no holes to drill, simple and efficient works great. I would recommend this product
Very short wire but seems to work.
its just an wire antenna, but it works very well, so no complaints. would recommend to anyone that is looking for a flexible antenna that can be hidden.
Answer: Hello, Mr. Gostl,The only photo I could find of this antenna is the one that Amazon uses, of the coiled-up assembly. I found a couple sites on which the image could be enlarged, and I see that the antenna consists of two lengths of wire: a thick section, perhaps two feet long, starting at the "Motorola" plug connector that goes into the radio, and a thinner section, possibly about three to four feet long, continuing from the thick section.  I suspect the bare wire (or "pigtail," as it is usually called) is at the collar where the two thicknesses of wire meet.If this assumption is correct, the pigtail is intended to be grounded. The thicker section of wire is shielded, and the pigtail is attached to the shield.  By grounding that wire, the thick segment is protected from extraneous electrical signals generated inside the vehicle ("noise").  That ground wire should be attached to a bare metal surface that connects electrically to the body of the vehicle, at the point where the thinner wire, which is intended to be the actual antenna, exits from the vehicle's metal shell.  If it is inside a car, that point would be where the antenna (usually) meets the windshield or the back window.However the antenna is used, that pigtail (if it is what I describe) should definitely be grounded, otherwise the antenna will not function properly.If you have, or can take, a photograph of the wire, uncoiled, but perhaps folded back and forth two or three times, so that I can see its layout clearly, I can be more specific, or correct any misconceptions that are in this message. Alternatively, take a photo of the part of the antenna where the pigtail is located.Good luck.  Please let me know how your project turns out,Lew Miller
