Put it in the trunk and extend the antenna.
I have just picked up a Directed unit, for $14US no less. Good find.
I am tossed where to mount it. The choices are in the trunk with the computer, or up under the dash.
Of course, the trunk idea requires me to purchase an antenna extension. The dash option requires a serial cable extension + audio extension.
I am hoping others here have some valuable input as to what they have done and/or what option works better. It's bad enough trying to reduce the static the PSU causes me. I don't want to add to the headaches.
You will suffer a loss in signal strength if you extend the antenna (unless you use an antenna amp) or a loss in audio quality if you mount it under the dash. Its up to you which is more important.
Thanks folks. I get LOTS of static no matter what I do. It is worth mentioning that I had this static using the stock head unit as well. For sure this is radio interference/static, not engine whine.
I have verified that the stock antenna amp is working. When I remove power from it all stations are worse-to-non-existant. I have now mounted everything in the trunk. Ran an antenna extension to the Directed unit, hooked it in. All parts use a common ground point, and I have also inserted a ground-loop isolator in the audio line since without it I get a small amount of alternator whine. I still have lots of static.
I made my own "antenna" wire, inserted it into the Directed radio, held it and moved it around the outside of the car. And, just like rabbit ears on a TV, if I move it around I can get better reception on some stations.
I know the PC is making reception poor, as it is clear with it off (and radio direct to amp) but the wire experiment seems to tell me that adding in an extra OEM antenna amp may help me out. I ordered one and we will see. Failing that, I'm not sure what to do next. While I have been an electronic tech, a couple of the techs here at work are going to offer up their opinions as well.
I know there are other threads on this site trying to deal with static, and there are just about as many suggestions as there are people with the issue. I've put in power line chokes/filters, clamp on ferrite thingys, seperated audio and digital lines, grounded to common points, etc. The additional antenna amp is about the last thing for me to try.
I have my Visteon (and XMPCR and Mitch's UAS) mounted inside my PC case and I have no problems with noise of any kind. I use an antenna extension with the stock Tacoma antenna and I DO notice a reception loss out on the edge of town. Betcha a buck you have a bad ground somewhere. It took me a couple of months to get mine all sorted, and accept the fact that you HAVE to use quality cables, but my system is buzz-free. The only power filter I use is on the main from the battery. If possible, get all your peripherals to a common ground. I use power distro blocks to/from the battery and it makes all the difference in the world.
Just my experience, hope it helps.
Thanks VegasGuy. I have all pieces in the trunk. All power ground is connected to the same frame point.
In my 2003 Altima, there is apparently two sources to power the factory antenna amplifier. There is a tracer wire along with the antenna wire that has 12V, and removing that (as mentioned) makes things worse. However, if I also power the "power antenna wire" that was supplied by the head unit, it is even better. I assumed that this was to raise/lower a power antenna, but apparently it is more than that.
Now I have much better reception, just not quite there.
UPDATE: I bit the bullet, and drilled a hole in the car body, and put in an OEM antenna. On the top of one of the rear fenders/quarter-panel. Nice and close to the radio module
WHAT A DIFFERENCE. This thing blows Nissan's stock window antenna out of the water. I now see some HD stations too (I'm in Canada but very close to the border).
I even tried an in-line booster but that actually degraded the signal.
I'm a happy camper with that now. By the time 0.8 comes out with optimization, updated skins, and I pick up GMPC, StreetDeck can rest-in-piece
