Product Description
Accessories
a. One dual band signal booster;
b. One indoor antenna;
c. One outdoor antenna;
d. 20meter cable and 5meter cable;
e. User manual;
f. Power adapter.
Technique supporting:
1. If still no signal receipt after activated repeater,please check if outdoor antenna point to signal tower or elsewhere have strong signal and check if strength achieve -70dBm.
2. If cannot call out,please adjust the direction of outdoor antenna.
3. If the strength is not steady,please check if outdoor and indoor antennas are too close;please ensure the outdoor antenna and indoor antenna have distance of 20meters at least,with a wall between and not in a same horizontal line.
It could also improve indoor electromagnetism environments, protract cellular battery life and reduce radiation of cellphones. A mobile phone repeater is ideal for house, home, office use.
