RF Transmissivity Question
This stuff...
http://analog-innovations.com/SED/BehindTheMirror.jpg screen printed (?) on your windshield behind your rear-view mirror. What is it? If I locate a radar detector behind it, will it significantly attenuate the radar signal strength ?:-) ...Jim Thompson -- | James E.Thompson, P.E. | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 Skype: Contacts Only | | | Voice480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine Sometimes I even put it in the food |

Its speckled on the edges to blend in. Laser yes, radar probably. The Tint also affects performance. Cheers |

As in looking at the mirror at a specific orientation could have the sun just past it. That keeps the glare from happening, allowing one to utilize the mirror trouble free. Optically speaking. I doubt seriously that it was metallic ink or that it would be anything other than transparent to RF. |

This stuff... http://analog-innovations.com/SED/BehindTheMirror.jpg screen printed (?) on your windshield behind your rear-view mirror. What is it? It doesn't appear to be a radio antenna. Possibly a sun screen to block sunlight that would otherwise leak between the sun visors and interfere with the use of the rear view mirror. If I locate a radar detector behind it, will it significantly attenuate the radar signal strength ?:-) Depends on what its made out of. If its metallic, then I'd guess 'Yes'. Find one of those annoying radar speed signs (fixed, low power, continuous source*). Park just at the threshold of your detector's picking it up. Move the detector back and forth from behind this screen to clear windshield and see if that makes a difference. *Be careful about assuming that these signs use a constant transmit level. One in my neighborhood pulses until it detects an oncoming vehicle. Then it switches to continuous mode. -- Paul Hovnanian ---------------------------------------------------------------------- Have gnu, will travel. |

That must be a ****ing Ford. You know... the idiots that used the same, runny windshield putty for twenty years after ALL of their customers complained about it. They ain't real bright. Also, why do you think an 8 inch square patch is needed to curb light from hitting a 1 inch square glue area? I'd say that you made it up. |
