Note: This is the biography from the back of my book "Designing RF cOmbining Systems for Shared Radio Sites".

Ian Graham is a seasoned RF design professional with a wealth of experience spanning over 35 years in the field. His expertise covers a diverse range of
industries, including avionics, military, mission critical (public safety and utilities), and commercial markets. Ian holds a Higher National Diploma (HND)
in electronics and telecommunications with distinction grades from Basildon College of Further Education. With a lifelong dedication to advancing radio
technology and a passion for sharing knowledge, Ian continues to make a significant impact in the world of RF engineering. His contributions have helped
shape the way we communicate and connect in today’s interconnected world.
Designing RF Combining Systems for Shared Radio Sites provides all of the background needed to design site-specific transmit and receive radio frequency (RF) combining systems at crowded RF sites. It will help engineers at all levels
to design site RF combining systems that do not cause or suffer interference as a result of other radio systems already installed at the site, and thereby achieve the goal of maximal coverage.
Representing the author’s decades of experience working in RF circuit, product and system design in the military, and public safety and critical infrastructure sectors, the book lays out the types of interferences that can occur when a number of transmitters and receivers belonging to different land mobile radio (LMR) systems are colocated. It illustrates how to survey the sites so that you know what high-level interfering signals your system will be exposed to, and then shows you how to use that information to design your base station antenna and combining systems at each site in your network for minimum interference potential and hence maximum coverage at minimum cost.
