After doing most of the work to add a heater core to my fresh air box, 3D printing some cool parts, fabbing the lines and buying everything else I need, I thought "do I really want all this when what I really need is a simple defrost function?"
I mean, I live in CA, don't drive the car if it's super cold or raining and I have heated seats. So the answer is "no, not gonna do it." Instead, I'm going to order 2 heated windshields (one for the LS car, one for the Ferrari build) from Heated Windsceens / Ricky Evans Motorsports in the UK: www.heatedwindscreen.com From their site: Is my windscreen going to be fully road legal? Yes - A lot of our heated windscreens are designing for motorsport use, however all of our products are fully road legal with all the correct markings for use on roads all over the world. Cost is currently about $400 US plus shipping. When I told them I wanted two, they said they have to put them on a pallet and the shipping cost would stay the same if it's two or up to 5 or 6. So... Anyone interested in a heated windshield? As far as needed wiring, here's the response I got when I asked about wiring it: To get the best performance from the screen it’s a 25A fuse and relay both sides to a single switch, you can do just a single circuit and rate it higher, attached the inner two wires on the screen but then it will take longer to warm up. PM me if you're interested and we can work out the details. |

Are these laminated clear elements? Any photos?
It's a common racer trick to buy a rear window defrost grid and install it on the inside of the front windshield. Don't even notice it while driver after initial surprise. |

Don't even notice it while driver after initial surprise. @GregAmy - Here's what they say on their site: Our heated windscreens aim to eliminate condensation, de-mist and speed up de-icing of the glass, allowing for a clearer and safer view of the road ahead. This could be the difference between winning the World Rally Championship or simply giving yourself 10 minutes extra in bed on a cold winter's day. The heated windscreens use almost invisible tungsten elements which work to increase the surface temperature of the glass, and in turn quickly clears the screen increasing visibility. With the exception of a few, all of our screens use a dual heating system meaning that there is a live and an earth wire on each side of the heated windscreen, each one will power half of the screen. If you are unsure please contact us to confirm if you have a single or dual element screen. |

I contacted the manufacturer asking:
"I was wondering if your wired windscreens could be used as a radio antenna?" His reply: "Hi Jeff, Had a chat with Ricky and if you got an amplifier off like an old Saphire Sierra then yes this actually could work. I couldn’t say if the heated function and everything would all function at the same time but in theory yes. Thanks, Dan" Ricky Evans Motorsport Ltd Unit 11, Roman Park Claymore , Tame Valley Ind Est Tamworth Staffs B77 5DQ Tele 0044(0)1827283688 email sales@heatedwindscreen.com |

AM is vertically polariazed & FM/TV is horizontally polarized. This gets partially scrambled as the fields propagate & bounce around. |

A diagonal element orientation will work for both polarizations, but with reduced SNR. |
