250K Quad Band O-DAS Kit

Covers 250,000 sqft of Outdoor Space

Product Overview

JDTECK's JDIR-LCPA-ODK-250 Series Cellular Repeater Kit is a high-powered, gain adjustable quad band repeater system designed to provide enhanced outdoor coverage for Voice, 3G and 4G LTE to a 250,000 sqft space. (500ft out from each service antenna). It is perfect for use in commercial and rural applications like drilling rigs, remote construction sites, RV camp grounds as well as remote residential locations like ranches and remote communities. Built into the IP65 rated head-end enclosure is a pre-amplifier which is designed specifically for weak input signals.  The repeater features individually assigned Uplink and Downlink attenuation adjustment DIP switches for each frequency band. This allows the user to optimize the output signals for the various bands supported by the system.

The donor antenna is a log periodic with metal canopy shield. This not only aids in capturing a weak signal, but helps increase RF isolation between the transmit and receive signals. The service antennas are high gain 60 degree beam-width panel antennas (2)  designed to provide maximum coverage of the space. The user may also opt to remove the 2-way splitter, connect just one service antenna which will narrow the coverage width, but effectively double the distance of coverage. 

The kit is supplied with everything needed for rapid deployment excluding the poles / towers to mount the the antennas on. Mounting the donor and service antennas on existing structures like a building, water tower or any other tall structure is also possible, but careful placement and orientation of each antenna is very important to avoid signal oscillation. 

In the standard kit, the donor cable length is 100ft and the service cables are 50ft each, however these can be customized as needed at the time of placing your order. The grade of the donor cable is 600 Series coax whereas the grade of the service cables is 400 Series.

250K Quad Band O-DAS Kit

To maintain safe and specific output signal levels, this advanced repeater has built-in AGC (Automatic Gain Control) and ALC (Automatic Limit Control) circuits which can automatically control the gain of the repeater within a 15dB range depending on the RF environmental conditions. In addition, it also has built-in attenuation dip switches that allow you to manually attenuate (fine tune) the repeater's uplink and downlink channels in 1db increments up to 31dB, using color changing LED's as a status indicator. These Alarm LED's are used as a guide to prevent your installation from re-producing errors due to excessive input signal strength if a pre-amp is used, or from signal oscillation due to the indoor antenna and outdoor antenna being too close to each other, which can have adverse effects on a base station and greatly impede system performance. 

A Network Safe / MUTE™ feature comes standard with this repeater to protect the cellular network. In short, the repeater will stop transmitting if any errors or signal oscillation is detected within 2-4 sec of detection. It will cycle for 30 sec then attempt to transmit again. If no adjustment in gain has been made to correct the error within the 30 sec MUTE cycle, the system will again shut down after 5 sec. It will run this sequence for a total of 3 times and then shut down completely.  Power cycling  the unit will reset this sequence.

This repeater is designed to be transparent to the network and will therefore support the same number of calls the serving sector of the BTS the donor antenna is aimed at.
