Actually, I still use rabbit ear antennas. And I live in a weak signal area for both cell phones and televisions.
You do not have to have physical contact with an antenna to improve its signal. Otherwise my reception wouldn't improve when I actually enter the room with the antenna. Reception also changes depending on how I sit in the chair. Some channels come in better when I place my arms and legs certain ways despite not being next to the antenna.
It's weird, but true.
And yes there is foil on the antenna posts that I've shaped a certain way. I've also noticed that my reception will also improve when my neighbor comes home and parks their car outside my window. When their car is here, I can get channels that won't come in at all otherwise. It's annoying when my neighbor leaves in the middle of a good show.
So obviously placing things somewhere in proximity will help.
I've also used the antenna stickers for cell phone reception that others say don't work. With my reception, I had nothing to lose.
I haven't used them on every phone I've had, but I have used them on 3 phones. Those particular phones always dropped calls and never worked at my house. The reception was so terrible that if the phone did manage to ring when someone called, it would drop the call by the time you said hello.
After placing the stickers inside the phone's battery compartment, the phones were suddenly reliable and never dropped calls again.
I've used them on a flip phone, a HTC windows phone, and a HTC Android phone.
Sure I was skeptical. But when you have something that won't work, what have you got to lose by trying? $7 wasn't much of a gamble on a sticker.
So, I'll reserve judgement on this new case until after it is released and publicly tested.
Just like the stickers had mixed results depending on the user, the phone, the service provider, and the geographic area, these cases will likely help some people.
