Metra Electronics 44-PW22 Motorized AM/FM Fully Automatic Power Antenna

Good replacement part
Works great with a little alterations to the wiring converting to the original factory plugs.

Works fine, and it is universal — almost!
The Metra 44-PW22 works fine for me as a replacement for the original antenna. For the car I was working on, a Jaguar XJS, I could only find two alternatives to the very expensive OEM replacement: One that is not automatic, and this one. This one does exactly what it is supposed to do, and for the price, I am very satisfied with this product. Note I just recently installed it, and so cannot report on long term reliability.A few notes for people considering buying it:- For my car, it is considerably noisier than the original.- Wiring is simple, three wires: One always 12V (red), another 12V when the radio is turned on (blue), and ground.- The way it works is this: When the blue wire goes hot, the antenna goes up. When it reaches full extension, the motor continues to grind for a few seconds before quitting. When the blue wire goes cold, the antenna goes down. When it is fully retracted, the motor continues to grind for a few seconds before quitting.- The important thing to note about wiring is this: The blue wire requires 12V to raise the antenna. However, the input is not a low current logic signal, but rather a power signal. If your radio does not provide enough current to drive the blue signal, a relay or transistor switch is needed — and is not a part of this kit. (See more below.) I believe a truly universal automatic antenna ought to support a >low current< input signal, and provide the relay or switching transistor internally. This is my reason for the four star vs. five star rating.Notes specific to the Jag XJS:- This unit is NOT a mechanical drop-n replacement. It is a little shorter than the original. And although there are also two similar mounting screws and the drain tube outlet, they are not spaced or aligned the same as the original. As a result, you can't re-use the original bracket, but have to bend the provided mounting bracket strip into shape. It is important to get the vertical dimension right, but don't sweat the exact horizontal dimension between the screws attaching the bracket to the antenna and the car. You can rotate the bracket a bit to get the vertical alignment reasonable, and torque it down. With a single screw attachment, the result is not as sturdy as the original bracket, but it is adequate.- The Metra unit comes with a pivot assembly to abut the inside of the fender. For my car, I found it worked best to simply remove the pivot assembly altogether. I also re-used the original tubular screw from the outside of the fender. Make sure to sort all this out before you try to measure the vertical spacing for the bracket strip.- Regarding wiring, the OEM radio puts out a 12V signal when the radio is turned on. However, this signal can only source about 10 mA, and the voltage drops to about 5 V. I initially obtained a low-current relay that was supposed to switch with as little as 10 mA. However, when I wired it up, the source signal could not switch the relay on. It could keep it on once switched, but could not cause it to switch. So I had to backtrack and get a switching transistor instead. I used a TIP120 NPN. I ran the yellow/green wire from the car through a 1.5k resistor to the base of the transistor. Works like a champ. It's good practice to run a snubber diode from collector to emitter, but my initial test circuit worked without it, without immediate damage to the transistor.So in summary, depending on your car, this may be one of the few, and possibly the only choice available. The good news is that it works well at a reasonable price. It would be a five star rating for me, but I had to add some external components to get the automatic function with my radio. Not hard, but adds a bit to the cost, and definitely adds to the time/effort on the installation.

Good product
For some reason, I got the idea that this one had an antenna black in color, like I got for another car. I have no luck, even thought that was available in the past. Returned it.

Best antenna for the price.
This is a good antenna with all the hardware you need. It is however the second antenna I had to buy. the first one was shorted but I didn’t realize it until the was installed for a few months because the car was in a restoration shop. So. test it first. I did test it against other antennas with a rear mount location and that means 16 foot of cable and it picked up stations better than the mini rubber and a 18 inch metal antenna. So far i am happy with the product.

Me.gusto por q es lo mismo pero más barata le.quedo muy bien a mi eclipse gst convertible 2.0 1999

ya habia comprado dos artículos mas de Metra, crei que como los otros dos quedaban como guantes, supuse que en esta ocasión seria lo mismo, por lo que decidi cambiar la antena de mi auto, pues no funcionaba y estaba rota, lamentablemente resulto que el mastil la parte donde se ‘guarda’ es demasiado corta, por esta razón no logra salir de la carroceria, debido a que (en mi caso) antes de llegar al orificio de la antena, hay un orificio interior que no permite subir mas la antena, y por ser de un mástil mas corto que el original no fue posible sujetarla de la parte superior, a mi parecer va a ser necesario recortar parte de la carrocería interior para poder subir mas el mastil y a su vez poder sujetarlo desde arriba/afuera de la carroceria del auto; si no lo devolví fue por el gasto que hice y el tiempo tan tardado de devolución de artículos internacionales ya tengo mas de dos semanas que devolvi un articulo y no pasa de las aduanas
