PKI 2250Print

The PKI 2250 portable crossband repeater is primarily designed for extending the range of low power monitoring devices. Due to its capacity to work from three different types of power supply this system is suitable for work inside buildings, in cars and in the field – independent of supply conditions. The electrical input characteristics of the 3 channel receiver section of PKI 2250 are adapted to PKI´s crystal stabilised low power transmitters. With the high output power of the PKI 2250 a distance of up to 15 km may be
bridged under ideal conditions. The totally selectable transmitter/receiver frequency pairs, various power supply adaptations and direct listen-into possibility make this system easy to operate and versatile for any kind of surveillance task. A hand-held 3-channel receiver for the outgoing frequencies of the PKI 2250 is included in the set as well as every necessary high gain directional antenna plus tripods (transmitting and receiving).
