Nokia N91 Cell Phone Amplifier (Aftermarket Wireless Product)
 Nokia N91 Cell Phone Amplifier/ Wireless Repeater: Antenna signal amplifier/ cell repeater is an RF antenna amplifier and RF transmitter for Nokia N91 with required RF cables (Nokia N91 cellular amplifier/ cell phone signal repeater is an aftermarket Nokia N91 wireless product). Nokia N91 bi-directional amplifier/ cell phone repeater greatly improves signal strength inside a vehicle when using your Nokia N91 cellphone. Using RF electronics, Nokia N91 antenna amplifier does this without physical connection to your phone! It even allows multiple Nokia N91 phones to be used simultaneously with this RF power amplifier for increased reception attributed to this high power amplifier with 3 Watts maximum output power (cell site controlled) and tuned precisely for Nokia N91 phones!
RF signal is received by Nokia N91 external cell phone antenna (not included) from the cell site. It is then amplified by this Nokia N91 cell phone signal amplifier and repeated to your Nokia N91 phone via the inside slim low profile antenna (included). When your Nokia N91 transmits, the signal is received by the same inside antenna, amplified by this Nokia N91 cellular amplifier, then repeated to the cell site via the outside RF transmitter antenna ("Magnet-mount" outside RF wireless phone antenna suggested. Sold separately. Not included with this Nokia N91 cellular phone amplifier purchase). RF parts included with Nokia N91 bidirectional amplifier/ cellular repeater purchase include two RG-174 RF connector cables with RF adapters to connect to Nokia N91 signal amplifier (10 ft. & 6 ft.), 12v DC power supply cord for any cigarette lighter plug adapter (to use at home or office building, buy AC/DC converter sold separately), and a slim antenna with smooth edges for discreet placement between seats or a similar position at suggested shoulder level in a vertical position for best 1-2 ft radiating pattern of this RF system which could boost reception for more than one Nokia N91 phone within its 1 to 2 ft. range. Operate Nokia N91 phone wirelessly with no physical connection to Nokia N91 phone! Ideal for use in car, large truck, boat, bus, mobile home or an RV travel trailer.
Safe overload protection circuit offers automatic reset whenever overload occurs on this Nokia N91 bidirectional amplifier. RF shielding also occurs when using this RF receiver and transmitter: Nokia N91 phones vary their power output based on their proximity to cell sites and this RF technology makes Nokia N91 phones lower their power output simulating an RF shield because it simulates proximity to a cell site thereby resulting in safer Nokia N91 phones and longer battery life of Nokia N91 phones.
