CTI has extensive work experience with most major North American and European TV broadcast antenna manufacturing firms. This experience, coupled with extensive design efforts on directional, nondirectional, single frequency and master antenna systems has placed CTI in a position to offer expert RF engineering design services to broadcasters, tower owners and management companies. In 2003/2004 CTI subcontracted to Riser Management Services of Burlington, Vermont the RF design specification services which resulted in the implementation of two new UHF and two new VHF master antenna systems for The Durst Organization’s 4Times Square facility in New York City. Partnering with Riser Management Systems on 4 Times Square is but one example of the benefits that CTI can bring to clients through effective partnerships.
