I am looking for a DIY mobile signal boosting circuit for my home. I just need to boost 2G signals in my house (required range – 7-10 meters). There are a few circuits online but I don’t know if they actually work. If anyone has made a 2G signal booster/ used any online circuit with success, pls. point me towards the same.
But I think there is no simple solution.
* It´s rather high frequency,
* it needs to "amplify" in both directions,
* it should not interfere it´s own receiver/transmitter
* and it should not interfere with other HF sources
