Has anyone tried Kapton Polyimide tape to mitigate the signal attenuation?

    Has anyone tried Kapton Polyimide tape (a la Anandtech) to mitigate the signal attenuation on their iPhone4? Is it possible to use an fine-tipped X-Acto knife to cut all the appropriate openings? Probably pretty tedious but is it do able? The gold color doesn't look bad.

    I dunno, but the full Zagg invisible shield seems to have mitigated the problem on my phone.

    Before I applied it, I would drop calls here at work. Since on, problem hasn't occurred...bars drop only 1-2 instead of 4-5.

    Three layers of electrical tape didn't help me. I doubt something this thin will.

    Well, there are 2 issues here:

    1) Bridging the gap between the 2 antennas detunes them - this issue is resolved by a case or tape
    2) Cupping your hand around any antenna degrades the signal. This is the issue that ANY radio device will suffer from and will not be resolved by a case or tape

    Issue #1 is what makes the iPhone unique and causes most of the problems. Issue #2 is minor but is what keeps people bitching and saying "a bumper doesn't fix the issue!" It most likely won't cause dropped calls except where the signal is already very weak.

    I was wondering how this work if you placed the tape on the inside of one of those bumpers:confused:
