We live in a rural area with Tesco
poor signal – maximum two bars inside. I bought this booster after calling the customer service for a recommendation cos couldn’t decide on a model to choose for my purposes and was said that this booster LCD 300GD might suit me perfectly well. When it arrived (within approximately 6 days) couldn’t wait but test it straight away. My signal jumped 2 bars in strength straight away though the outdoor antenna was not properly fixed. Thus my call quality has improved drastically and I’m no longer irritated with Tesco poor coverage. I would definitely recommend this device (or other products of this seller) to anyone facing the same Tesco signal problems.
