Got tint, now radio sucks - Page 2

just try to get the tint guy to cut you a deal on retinting it without metallic tint

Ummm, I don't think that's what he meant. I think he meant if you had a radar detector inside your car and you had metallic tinted windows your radar detector would be less sensitive because of the shielding from the window tint...

I apologize, I was making an assumption about radar technology that was incorrect.

I was assuming that police radar guns used sonic energy. I am actually working with sonic technology in an electronics research project so I assumed that I new a lot more about the technology than I actually did.

In reality a radar detector uses radio energy, fundamentally different from sonic energy. Knowing this, I have to admit that Excalibur was right all along. The "Faraday cage" effect described by 07civicex would severely hamper the ability of commercial radar detectors to see police radar guns.

I listen to skip waves off the Gulf of Mexico. I am assuming it is either Cubans or Mexicans talking. And sometimes some guy screaming gospel in what sounds like a garage.

EDIT: Use Madico films. Hard to find, best around.

i'm glad i saw this...i was thinking about the mirrored tint, and wondered about the radio and radar interference. guess i'll keep the windows clear instead.

Old one but so to inform you as well.. I'm dealing with it now.. Installed Llumar ATR reflective 40..

My question is which line or lines on an 08 Si Sedan are the antenna and which are the defogger??

I googled.. found this bit of info about trying to isolate the two: AM Radio Reception and Tint

"It's a given today that metalized film may interfere with AM radio reception in the event the antenna is located on the back glass. The phenomena of quasi-connecting the antenna to the defroster grid (which grounds the signal to the chassis) after installation of metalized film to the back glass is believed to be part of the problem. This tip is NOT for other electronics such as GPS, XM radio, Wi-Fi, Cell Phone, etc., which are affected by the RF shielding capacity of a metal film.

Locate the uppermost defroster line (this would be the last of many that travels completely across the back glass with no breaks in its line). Carefully cut a seam into the film, either before or after installation, running above, parallel and adjacent to the uppermost defroster line (not the antenna line). This breaks the quasi-connection and grounding effect between the film, antenna and defroster grid.

If this does not work, you may have to resort to extreme measures: 1) Cut another seam BELOW parallel and adjacent to the uppermost defroster line and remove the sliver of film from that particular defrost line. 2) R & R with a non-conductive film construction such as straight-dyed, pigmented polyester, IR absorbing film or a combination of these.

I have even had a consumer ask me to remove a sliver of film over the entire antenna line, which for that vehicle was an upside down T and easily done. Other more elaborate antenna grids would be most difficult and time consuming.

Of course, the consumer should be consulted and advised as to the trade off between radio reception, film performance, and 'possibly' looks (In this day and age of one-piece installs)."

I had mine tinted up a few months ago now, and while radio reception seems fine (I almost never use it with my iPhone plugged in the glovebox, my wife does though). I believe my tint is non-metalic though. What DOES interefere with it now is if I turn on the rear window defroster while using the radio. I laughed when we finally figured it out (my wife had been complaining about it).

maybe they damaged it while installing the tint? such as the part where they cut the tint to shape

***Cybergypsy*** · 05-07-2008, 07:18 PM

a no no for navi too never use metallic
