does it block signal at all?

I did not experience any signal problems at all. Outstanding case for IPhone 5S.

It will amplify the signal but will also amplify the noise. It won't 'clean up' the signal per se. Some T.V.s won't program a station if the signal is too weak. It will help with that.

No. Interference trap blocks unwanted radio transmissions such as nearby FM radio stations. This device blocks 60 Hz electric mains hum that you might hear as a buzzing noise in your speakers.

This splitter will amplify any signal supplied to it. However, it won't help with reception. If the input signal to the splitter is intermittent or noisy, the splitter won't help with that. In my case, the cable into my house had several splits before it came to my cable modem. Installing this splitter boosted a weak, but otherwise intact, signal back up to a useable level.

I haven't. Encountered a signal problem of any kind. However, after checking with my carrier ATT the area I live in is saturated with towers. I stated this to say that this may be the reason why I haven't experienced any signal problem. But the answer to your question is "no, haven't had a problem with signal interference."

Just yesterday my grandson noticed that he had signal 2 blocks away, driving away. There was a large brick building between us and the house. If you have lath and plaster walls, that might reduce your signal a bit. I'd guess it will work just fine.

No. It sucks. You need its reciever to get the signal and even right next to it the signal is weak.

I have no issues with it. Infact I love it. It does not block any ports or anything.

No, Think of It as a laptop or moblie device. It picks up all signals you get to choose which one to connect to. once connected you are in. I have had no problems with this device, works great.

No it doesn't, plus i cannot understand how a battery can affect the signal reception, so my answer again is No it does not affect signal in any way.

Yes as long as you done have concrtetr or steel construction to interfere with the signal. If you do you need to be pretty close in range.

It blocks everything and every number EXCEPT the ones you have programmed in. If the number calling is private or blocked, it does not make through

no, it does not. I have my complete 2nd floor covered with it, and signal is great

I've never had that problem. My only issue is the case blocking my signal at times.

Yes, if you program it to block all unidentified calls, it does. It also blocks specific numbers or even whole area codes, up to the limit of its memory.

Yes it does. You will have to watch for interference, I've found I often have to find a different channel than the default channel because it is VERY prone to being triggered by random transmissions at certain sites.

To be honest I believe it only effects wifi slightly. I havent measured the actual signal loss but ive never lost I signal with the silicone case. I believe I loose about 1/8 or my signal at the most and its not really noticeable so you should be fine! Hope this response helped:)
