Quick delivery. Clear instructions and options to properly install antenna

This is absolute garbage. Worked fine the first time used. Second time it was making multiple loud clicks before stopping to go up or down. Third time it just non-stop tried to go up or down clicking over and over until you remove power from it. THIS after having to send the first one back because it was missing pieces that were supposed to come with it.

It contained all of the mounting hardware needed including straps to secure it.
Make sure your vehicle has the right antenna connection for this one which is a screw on connection at the mast. Many vehicles have a male style push connector which will not work on this product.
Also nice touch that the long wiring harness can disconnect from the leads near the antenna allowing you to shorten the cable as you see fit.

Great product, great price, great vendor = Great DEAL! I’m impressed! Thanks…
EDIT: I have purchased this antenna 2 times before without a problem.
This time this antenna came in a plastic bag (the others were received in their original packing and box) and it was not complete – it was missing parts and the mounting bracket was bent and twisted like somebody tried to install it before. I’m guessing it was a customer return.
It wasn’t until I tried to install it that I discovered this is not even the same antenna-the others had an antenna shaft that was two inches longer. This one is too short to come up through the fender.
I decided I was going to make one out of this one and the two I have, and it doesn’t even function.
Somebody messed it up, then sent it back.
This one is only getting one star. (The other two were perfect if not short lived)

I bought one of these PW22 power antennas for my 2003 Corvette C5 Z06 in October 2012 from a different merchant, after my previous model HCA350B from JC Whitney had died after a few years. The HCA350B was no longer available, and I figured I’d give a different brand / model a try. Well the PW22 lasted 36 months, same length of time. It just died, but I couldn’t find anything with superior ratings, so I just bought another PW22, this time from Amazon, and installed it earlier today. It took about an hour to install, and it works great. But I doubt it will last over 3 years.
By the way, as I was installing the second PW22 a little while ago, I got to see what had happened to the first one. When it failed, the flexible drive rack inside the antenna house burst out of the periphery of the housing. So about two feet of the plastic toothy element was tangled with the brake light wiring. Fortunately, no harm done.
Noteworthy is the fact that my HCA350B and first PW22 power antennas both failed in a manner that might drain the battery. When I turned off the car, the antenna retracted but the motor would not stop running; The first time I was in my garage and ran and got a pair of wire cutters and snipped the red wire I had run beside the passenger door. I installed a wire nut later in case the PW22 failed the same way, which it did. And I was parking at the gym to work out when it happened, no wire cutters. So providing a way to quickly disconnect the power paid off.

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.

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

The project tuned out great. Depending upon the body design and access your antenna replacement project may be easy our complex. My brother does auto stereo installations so I was able to get helpful hints like don’t throw anything from old antenna away or loose any old parts until your install is functional. I had to modify the old bracket to accommodate the new antenna assembly. Additionally, the company sends an array antenna adapters, so I had to use the old one with some significant modifications. The new rig works well, but it’s not as quiet as the Los one.

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.
