Our company is the leading Italian Antenna Manufacturing company which has gained in the last years a growing place in the market, due its excellence in design and supply of turn-key projects for DVB-T switch-off.Itech develops high performance Antenna Systems in UHF, VHF and FM bands. It is the only company who manufacture and develop the whole product line: panels, dipoles, Yagi, balanced and unbalanced power dividers, phased cables, flanges, rigid lines, filters, combiners and patch-panels along with custom designed radomes and steel structures for specific projects.Thanks to Italian particular territory, Itech has been involved in many projects for antenna special design, becoming a leader in notch design, electrical tilt definition and custom Vertical and Horizontal diagram special design.We developed special antennas for USA, where delivered antennas for the most important transmitting sites such as Sutro Tower, Boca Raton, Minneapolis, Omaha, etc. Moreover, Itech is a key reference for the radiofrequency design and planning with high end software specially designed for broadcasting market . The antenna system have been developed to comply with all the international standards and with the best state of the art technology. Products• Panels and Yagis in FM, VHF, UHF Band• Hybrids and combiners; Power splitters up to 6-1/8” (60 KW)Design / Simulations / Manufacture• Proprietary software development for antenna system design• Design and realization of mechanical structure (tower, spines and poles)• In factory antenna system assembly & Testing (VSWR; radiation patterns)
