Technology Inc. (CTI) pioneered rebroadcast technology
and developed the first ever AM tunnel rebroadcast
system in 1962.
CTI is a leader in rebroadcasting, as a designer
and manufacturer of AM & FM, VHF, UHF & 800-MHz
Rebroadcast Systems and AM&FM Radiators (Tunnel
Antennas) and as an integrator of rebroadcast
radio systems for highway tunnels, in-building
and subway systems.
CTI's current Mark systems are the result of more than
40 years of development and operational evaluation.
There are over 50 current Mark Rebroadcast Installations.
Some have over 10 years of continuous, failure
IV Narrowband Class-A BDA provides a cost effective
legal alternative to Broadband Class-B boosters,
which are illegal in most urban
settings. The Mark IV can also be used in retrofit
versions to upgrade Class-B boosters to the required
The Mark IV meets the demands of current and future digital radio systems
since the MARK-IV DIGITAL uplink path filters can be programmed to transmit only your assigned frequencies as a Class-A Signal Booster.
Narrowband delay is less than 110 uSec delay, in
addition the downlink path channel filters can be
broader to accommodate the fastest digital
modulation requirements e.g. within buildings.
CTI has designed and integrated two-way radio
rebroadcast systems using various platforms: Base
Stations, BDA (Broadband Boosters) and OFR (On-
Frequency-Repeaters) for Public Safety and Cellular
customers. Our background as system integrators
adds to our experience as designers and manufacturers
of rebroadcast systems.
