I hope this is the right place to ask this question. I have looked a four or five sites about handset phones but am lost. We have a Uniden 900Mhz dual handset and the range is suppose to be around 200 feet. Well, at about 40-50 feet, if I am standing in the right position and have my ear cocked the right way, I can here the phone okay but usually I get a lot of static and do not get near the 200 feet range. I have tried moving the phone base to different spots in the house but unless I am fairly close I get static. Are there differences in frequencies with one being better than another? Are some brands better than others? Any help would be appreciated.

Thanks
