This paper presents results of using a drone-based measurement system to verify actual in-situ antenna radiation patterns for diagnosis and comparison to the intended design for the TV and Radio Broadcasting industry. This specific antenna verification solution uses an unmanned aerial vehicle (UAV) with integrated antenna, receiver and software. Measurements are taken in the far-field of ‘live’ existing high-powered broadcast systems in order to retrieve the azimuth and elevation patterns as well as absolute effective radiated power (ERP) for each service under measurement. Results show greater accuracy, timeliness and cost efficiency compared to traditional measurement techniques (i.e. land-based or manned aircraft based surveys) due to advances in positional accuracy, receiver resolutions and portability. Discrepancies between measured and theoretical patterns outline the potential for installation or manufacturer errors (e.g. incorrect feeder phasing). Use of this solution will enable government regulators, telecommunication network operators, broadcast integrators, infrastructure owners and defense communication/radar operators to verify and troubleshoot their antenna systems. Correcting any errors in operation allows for improved service reception, increased signal coverage and improved data reliability. Sample examples of over 600 measured broadcast services will be shown.
