KSaAuto 12V Car Antenna Booster Stereo FM AM Radio Signal Amplifier Amp for Car Vehicle Truck SUV Boat Marine UTV RV Accessories FM Amplifier Audio Radio Stereo Media Head Unit Receiver Hidden Antenna

I have had signal issues in my area (DMV) along with having a stubby type antenna on my Jeep.... I recently changed my radio to a double din; I added the antenna booster and WOW what a difference! I get many more stations than expected and works super well with my new radio. Highly Recommend.

This was the second unit I got and it still does not work. The antenna works ok without the booster, but nothing works with the booster. What a pain in the ass!!!

Works great

Was doubtful but it does what it says it does… boosts my radio station reception . Exactly what I was looking for

Boosted weak signal from NPR station. Oddly, others got weaker. Better than telescoping metal antenna.

Bought this on January 31, 2026 and installed it on my classic car. It worked well and amplified the signals. Last weekend (February 14th) the radio would not pick up any stations. Found out this booster had failed. Blue light was on so it had power. Removed it and the radio receives stations now. Did not even last 1 month.

I’ve had an issue with getting stations in my 2005 Subaru for 2 years. I did all I could to improve and rectify issues I had with a pinched cable to improve radio quality to only gain a little better signal. This is a complete game changer. It took ten minutes to install just the booster and I went from four clear channels to over a dozen. This has been a Great buy!!! The antenna that comes with the booster stinks, I compared it to the stock antenna and it was terrible. Yes I know you have to connect it to power and I had it connected to power, it still was really bad. If you need a booster to get better radio signals do not look any further, this is the booster for you. If your looking to replace your antenna and though the added booster would be good find a different antenna but this booster is Great! Thankfully I only needed the booster to get the radio clarity and signals I needed. The antenna went in the trash.

The custom autosound mfg. ANTUV-HIDEAWAY antenna has no amplification components on the circuit board. I tested it into the front end of my Ham rig which tunes down below the AM Broadcast band up into the VHF region. When I saw no improvement in signal strength, actually no signal, I opened it up to look at the circuitry. See the attached picture. There are no components on the other side of the circuit board just for info. I also put a RF signal into the input point on the board on the right and probed with my Oscilloscope throughout the circuit board pads from a commercial RF generator. There was no Radio frequency signal beyond the junction with components where the lower red wire comes into the circuit board. There was a spot on the left circuit board where a surface mount transistor could have been mounted but there was no sign of one ever being soldiered on the pads. The other antenna preamp did not noticeably amplify signals in the AM broadcast band. Usually signals for a broadcast receiver might be in the microvolt or greater region. I hold a commercial broadcast license and worked in AM-FM and TV broadcasting. To get a signal to the output plug I had to drive the input into many millivolt to volt level and the output signal was not linear in fact distorted. What I tested here is headed for the garbage can. If the manufacture wants to send me another circuit I will test and give a truthful comparison of db gain. These two amplifiers are not what was advertised from the way I read in the Amazon ad.

🤟🤟🤟 Sa fonction super bien rien à redire

Unit did not work as advertised.

Very good reception. No problem

Il y a une amélioration de la réception après l’installation de l’amplificateur

Fonctionne bien mais j’ai refait les soudures les câble était débranché
