As we all know the 'new' bumper shields the front radar better from snow, however it can still build up over the radar. Has anyone added a heater to the front to prevent this for long roadtrips? I was thinking about it and I don't think it would be super difficult. Obviously a metal plate would be counter productive, however if it was a mesh was < 1/10th of the wavelength of the radar it shouldn't be a faradaycage, however I am not sure how much of an impact it would have. Just some quick math. 77Ghz = 3.8mm wavelength, and a quick search shows for a faradaycage 1/10 to 1/20th of the wavelength is required, so it looks like you'd have to have a pretty fine mesh for it to completely block the radar. Idea #1, wirewound silicone mat Silicone Rubber Heater, wire wound, 5" x 5", 125 watts, 120v, 5 w/sq. in, 8" leads Pros: super easy, just need to glue it to the bumper in front of the radar Cons: might degrade the radar Idea #2, IR heater 5 inch Infrared Strip Heater, 500W Pros: won't mess with the radar Cons: way too expensive Idea #3, long heated strip along the top of othe bumper Pros: not in the way of radar Cons: it would only work if the melted snow above the radar was enough to come down and melt the snow building up in front of the radar. Idea #4, duct in warm air to heat the bumper from behind Pros: no interferance Cons: more complicated, will probably use a lot of power (compaired to just the headed pad) Has anyone already solved this problem? Does anyone know about a type of heated pad that is RF transparent? I see some pads that use kapton, however it looks like that is just the material used around metal wires.
