Can You Drill Glass For Car Phone Aerials?

Two of my bosses have Audi A8's. They have terrible mobile reception and we've found out that it's because the glass has a thin film of aluminium in I think for UV rays or something. It stops their e-tags working too.

Anyway, one of them wants me to get his roof drilled for an external aerial but I am concerned about creating a place for rust to start. I know there is lots of aluminium in these cars but surely there is steel too?

I thought it would be better to drill the glass. Can this be done? Does anyone know where I can get it done?

Thanks.

doooood! don't drill any holes anywhere. the external aerial just sticks on the outside of the glass, then you just need to feed a thin wire through a panel gap, seal gap or make a small gap and do through there. there is usually a way. drilling a hole in the screen you can't do as cracks will propogate from the hole, drilling the roof is pretty drastic too. call one of the mobile phone install guys I'm sure they can figure it out easy.

Well we tried one who installed an external aerial but it still goes through the glass without wires and it doesn't work.

Baron is right though. You can get external aerials that have the wires that run to the car kit. I think there is one in the merc.

There should be a dotted section on the windscreen near the rear view mirror - this section doesn't have the metal film and they should place their eTag brackets there. :P

As far as I know, Adam, the A8 has an all-aluminium body, because it's their flagship model. This could be another reason why the reception is compromised. Then again, it does reduce the risk of rust if they were to drill into the body.

True, I'm pretty sure all manufacturers leave a small section of windscreen "unprotected" for this purpose, and it's usually right under the rear-view mirror.

Yeah apparently they figured this out just after this model.

      From Japan and back to Europe, my sh*tbox R34 GTT

      Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.

      Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?

      I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
