Thanks for the help > Let me ask you guys something, since you seem to know your radios and wiring. I have Sirius radio. I can use it fine with my FM modulator, but as you probably know, the sound is much less than CD quality. On my (now traded in) Elantra, I used an in-line antenna adapter to pipe in the Sirius. Although it still relied on a FM modulator, the sound was much better - almost CD quality. When I got rid of the Elantra I removed the antenna adapter and tried to install it in my Sonata. With it in place, I had great sounding Sirius, but my AM reception was almost nothing, and my FM was very poor. Removing the adapter fixed that problem and I have left it alone ever since. Could the adapter interfere with the built-in antenna amp? Is there any way around that? Thanks for any help you can provide. I am thinking maybe this is some kind of grounding issue, but I tried a few things with no success. Of course, I wasn't aware of the antenna amp to begin with. Eric |
Re: 2006 Sonata - Antenna Amp?
It could be interfering with the proper passage of the signal along the
antenna wire. I'd think it'd need a built-in amp or some sort of pass-thru switch to prevent lack of reception. |

This is unlikely, as someone else here just replaced their radio with an aftermarket one, and I'm sure that does not provide a bias voltage. The switch for the modulator is likely cap. coupled which would block that voltage (if present). Measure from ground to the center pin from the radio. More likely is that either the switch isn't working - kill the power to the Sirius receiver, and see if there's any difference in reception on a sort of receivable FM station - NOT the channel Sirius is transmitting on - when the Sirius receiver is turned on. If not, the switch, or the switching output from the Sirius receiver is broken. If it gets worse when the Sirius receiver is on, and better, but not good when it's off, it's probably a problem with the cable between the switch and the car radio - assuming the tail from the switch is the side the car radio belongs on, and the "hole" in the switch is where the car radio antenna goes. The modulator from the Sirius is probably hot enough that the car radio can hear it, even if the cable is bad. |

I tested for voltage and have none (well, it actually shows 1 mV but I think my meter is just out of calibration). The adapter gives me the same reception on all AM/FM stations with or without the Sirius radio connected. Also, if it is connected, power on or off makes no difference. Yet I tested it all out on my Entourage, which I believe hasd the same antenna, and it worked fine. Weird. Eric |
