Signal and Coverage Analysis
The company will complete coverage and signal evaluation studies for new or existing broadcasting and communications facilities. RF propagation and signal coverage analysis for all broadcasting and communications frequency bands. Our wide experience in this field has led to the development of many special techniques for evaluation and analysis of special case path studies over obstructed paths and difficult terrain. With the latest in software and computer evaluation methods and terrain data bases, path analysis and propagation studies, including evaluation of existing facilities which have not achieved their desired coverage objectives can be undertaken.

Broadcast and Communication Site Design and Implementation
The company has been involved in many aspects of transmitter site design. The company has designed and supervised the construction of a number of major single and multi use, broadcast and communications transmission facilities. In addition to its own team of experts, the company has worked jointly with other professionals in this field to provide complete turnkey services.

Spectrum Management Studies
The use of the RF spectrum for broadcasting and communications requires a complex analysis of potential coverage areas integrated with the analysis of potential interference to other users of the band. D.E.M. Allen & Associates Ltd. has been involved in many aspects of RF spectrum allocation, assignment studies and planning to help achieve the best coverage consistent with meeting national and international interference and protection regulations.

RF Energy Studies and Surveys
Health and Welfare Canada, Safety Code 6 provides the guidelines for assessment of the "Limits of Human Exposure to Radiofrequency Electromagnetic Fields in the Frequency Range from 3 kHz to 300 GHz". Because of our involvement in many high power broadcasting sites in close proximity to major population centres, we have been at the forefront in the theoretical assessment and measurement of high density RF energy and determination of compliance with Safety Code 6.We are fully equipped to carry out calculations to predict levels of RF energy from existing or proposed transmitter sites and to carry out site measurement surveys in accordance with the exposure limit standards set by the appropriate regulatory authority.

Project Management, Communication and Testing
The Company has the expertise, field experience and equipment required to undertake the project management, commissioning, testing and evaluation of most broadcast and communications facilities.
