Founded in 1952, Hammett & Edison is a recognized leader for radio frequency engineering services.

Located from its inception near San Francisco, the firm presently has a professional staff of nine engineers, six of whom are registered as Professional Engineers.  They are supported by IT, field, and administrative personnel.  The firm is committed to the highest standards of engineering excellence and ethical conduct in the service of its clients.

H&E began with a focus on broadcast station coverage — obtaining, predicting, measuring, and improving signal coverage — and has developed a number of fields of specific expertise, including frequency allocation, transmitting site selection, and optimized antenna design.

With the advent of cellular telephone service in the 1980s, H&E responded to client needs with a growing focus on environmental compliance (RF exposure and acoustic noise) for wireless telecommunications base stations — calculations for proposed facilities and measurements for existing facilities, along with mitigation of conditions, where appropriate.  Clients include wireless carriers, cities and counties, and private landlords.
