Technical practice
From allocation to authorization.
Practical engineering support for broadcasters, attorneys, owners, and station groups—grounded in the applicable FCC rules and the realities of constructing and operating broadcast facilities.
FM & Translator Studies
Channel and site searches, spacing and contour studies, directional antenna showings, community coverage, interference review, and relocation analysis.
TV & LPTV
Full-power, Class A, LPTV, and TV translator engineering, including TVStudy analysis, channel evaluation, displacement, and facility-change exhibits.
FCC Applications
Technical preparation and support for construction permits, license applications, minor changes, STAs, extensions, amendments, and rule-compliance showings.
Allocation & Due Diligence
Early-stage feasibility, acquisition review, ownership and technical due diligence, upgrade potential, and identification of material engineering constraints.
Specialized Analysis
FAA tower-construction notices, RF exposure, antenna-pattern and elevation review, experimental facilities, and other non-routine broadcast matters.
The consulting approach
Engineering that supports a decision.
A useful study does more than produce a map or a calculation. It identifies the controlling facts, explains the constraint, and gives the client a practical path forward.
2,500+ facilitiesExperience supporting a broad and active portfolio across multiple broadcast services.
01
Rule-grounded
Technical work tied directly to the applicable FCC requirements.
02
Decision-ready
Clear conclusions, limitations, and next steps—not unexplained output.
03
Direct access
Work led by Timothy Z. Sawyer, with focused communication throughout.
04
Nationwide scope
Project support for broadcast facilities and counsel across the country.
Bring the engineering question.
Include the call sign, facility ID, proposed site or facility change, and the decision you need to make. We’ll start with the controlling technical issues.
