Overview
With the advent of FCC-permitted AM directional antenna performance verification using moment-method computer modeling, broadcast engineers now have a new and powerful tool at their disposal. Qualifying arrays can be modeled and adjusted to the calibrated model parameters in lieu of all the labor, time and uncertainty of adjusting and proofing them using the old cut-and-try method employing field intensity measurements. This webinar provides a detailed overview of the modeling process, including base impedance matrix and sample system calibration measurements, model construction/calibration and derivation of operating parameters from the calibrated model. The FCC requirements for moment-method license applications are also discussed.
Who Should Attend
- Engineers who are considering relicensing their arrays using MoM
- Those who operate MoM-licensed arrays that are facing biennial recertification
- Engineers who struggle with maintaining monitor points
- Operators of directional arrays with reradiators nearby
Goals and Deliverables
- Provide attendees with a good working knowledge of the modeling process
- Give participants the tools they need to assist their consulting engineers with an MoM application
- Debunk much if not all of the misinformation about MoM modeling/licensing that is out there
- Define clearly the eligibility of various antennas for modeling
- Afford participants a “peek under the hood” of the actual modeling process from start to finish
About Your Instructor – Cris Alexander, CPBE, AMD, DRB
Cris Alexander is director of engineering for Crawford Broadcasting Company. He began his career in broadcasting in Amarillo, TX, in the mid-1970s. Obtaining an FCC First Class Radiotelephone License, he worked in the engineering departments of AM, FM and TV stations in that market before moving to Dallas/Fort Worth, where he worked first in television and then in radio, landing in his present position with Crawford Broadcasting Company in 1984.
Alexander is a graduate of the Cleveland Institute of Electronics (CIE) Broadcast Engineering course. He is an SBE member, holds SBE Professional Broadcast Engineer (CPBE), AM Directional Specialist (AMD) and Digital Radio Broadcast Specialist (DRB) certifications and is certification chairman of the Denver SBE chapter. He is an associate member of the Association of Federal Communications Commission Consulting Engineers (AFCCE). He is a partner in Au Contraire Software, Ltd., a provider of broadcast engineering software and database services, including AM antenna modeling software.
