Loma Scientific International - MMDS Transmitters, Microwave Power Amplifiers and Broadcast Television Systems
A Broadband Wireless Access MMDS Transmitter Manufacturer and Systems Company

Company Background

Corporate HeadquartersFor nearly six decades, the principals of LOMA SCIENTIFIC INTERNATIONAL have served the needs of the telecommunications industry on all continents in over 40 countries. The company's founder, J. Patrick Loughboro, was instrumental in the creation of FCC rules permitting the use of spectrum for Instructional Television Fixed Service (ITFS), changing the way the world looks at education.

When the FCC decided to allocate part of the spectrum for commercial use (MDS), we were there to lead the way in the design and manufacture of quality equipment to meet the needs of this new industry. With the advent of Multichannel MDS, LOMA SCIENTIFIC INTERNATIONAL has excelled in the continued development and manufacture of its proven technology.

Power Amplifier Final TestLOMA SCIENTIFIC INTERNATIONAL is a leading manufacturer of state of the art transmission equipment for the broadcast industry. Our dedication to research and development is unmatched. As a result, we are the only manufacturer to incorporate a true "ULTRA-LINEAR" design philosophy into transmitters, the heart of any broadcast facility.
