Nokia 3650 Internal antenna Booster

Remember a while ago i mentioned how i get such bad reception with my nokia3650 inside my house, well on ebay i found this Internal antenna Booster which suppose to boost your reception and signal strentgh, i just ordered it off ebay for $1.50 + free shipping, if anyone interested just type in 3650 antenna in the ebay search and it will come up, theres a few for sale for the same price (practically nothing) with the buy now option. Just thought i would let use know. I'll let u know how it works when i get it...PEACE...shaolin

As you probably allready know, this so called booster is a fake,
how passive sticker could ever be amplifier?

Does it use magic aura for amplifying reception or is it just a worlds first perpetual-motion machine, doesn't need energy to give energy to others 😊 ?

Thank god you didin't loose much money or if you're here just advertising this product, shame on you!

Well technically by increasing the area of the internal antenna that the phone has it could increase reception. But generally you are right. A passive booster is most of the time just a piece of metal or plastic or goo or who knows what.

well anyways i'll let u know if it works once i get it, theres only way to find out right....peace

Hello 😊
Personally, i also think this is just a rip-off product..... BUT....
ever heared of a "Yagi" antenna? A TV-Antenna is such a Yagi..... And the Antenna here is also only a dipole, the loop-style element. All the others are indeed passive and can actually be removed, the antenna will still receive......
The more such elements you add (they have to be exactly calculated in their length and distance to others!) the higher your receiption level becomes, therefor there are such Antennas with only three elements, and others with 25 elements for the same frequency.....
The adding of such elements to the actual receiving one, the loop-stuled dipole, also add's the ability for the antenna to become directional, that's why you have to turn it untill you get best receipto. The more elements the antenna has, the more precise is this directional behaviour.
There are "reflectors" (usually only one element, but can also be two, three or even a metal net) behind the receiving dipole, and "directors" in front of it which can be from one to *unlimited* numbers. The more you have, the stronger the signal and the preciser the antenna.
Now, if this sticker thingy could act like such a "director", it might indeed boost the receiption, but to do so, it needs to painly precisely be applied to the phone, with the distance to the internal antenna having to be calculated to the receiving frequency of the used band. Just sticking it on *somewhere* does nothing but cost 1.50 $ 😊

PS i have experience in HAM and CB radio... thus my knowledge in Yagi's....
