Near-field measurements eliminate special FAA waivers, reduce impact of signal reflections on measurements for broadcasters seeking to verify antenna radiation characteristics
RAYMOND, Maine, September 15, 2020 — Dielectric has launched a new engineering service that enables drone operators to fully and accurately characterize Antenna azimuth and elevation performance without special waivers from the FAA. The service has been successfully beta-tested and is now “in production” at several broadcast tower sites.
The new service is a response to a common dilemma facing drone operators: To fully characterize an antenna’s elevation pattern, the drone flight must be performed in the elevation far-field, approximately several thousand feet from the antenna. Applications for FAA waivers have been stalled for more than 18 months in some cases, preventing the drone operator from completing measurements verifying antenna performance.
The less-attractive alternatives for broadcasters include close-in flights, which are accurate for azimuth only; or the less accurate and time-intensive ground-based techniques. Since the field measurements are reimbursable for “repacked” broadcasters in the USA, the delay in obtaining an FAA waiver can result not only in a repack project dragging on much longer than necessary, but also in the delayed identification of installation problems.
Dielectric engineers recognized that a new approach was needed. Realizing that no special waivers were required from the FAA for drone flights within the tower structure shield, Dielectric devised a method to confirm the antenna’s far-fieldelevation pattern, in addition to the azimuth pattern, from data gathered within that shield. This technique has an added advantage since far-field measurements are subject to signal reflections, multipath and interference, as are the more complicated ground-vehicle measurements.
“FAA rules place several restrictions on flying drones for commercial use. There is a 400-feet altitude restriction on commercial drone flights, unless the operator can fly the drone within a 400-foot radius around a structure, and does not fly higher than 400 feet above the top of that structure,” said John Schadler, Vice President of Engineering, Dielectric. “Unfortunately, waivers for these rules take many months to process, and may never be granted due to other restrictions. Ourtechnique solves the problem of getting a waiver beyond the FAA shield. That means no need to create flight plans and safety simulations, among other requirements that lengthen the approval process.”
Both near-field and far-field measurements allow broadcasters to verify azimuth radiation patterns for their TV antennas, and confirm that they are radiating as predicted and oriented properly on the tower. Dielectric’s approach calculates the near-field elevation pattern characteristics for comparison to the near-field drone measurement data, thus allowing a near-field measurement to accurately reflect elevation far-field performance.
Prior to a drone pilot taking flight, Dielectric engineers construct a full virtual model of the entire antenna, including tower support structure, based on final antenna and tower drawings. Using the company’s sophisticated high-frequency modeling software with the virtual model produces a detailed prediction of azimuth and elevation data at a given distance from the tower – at or within the 400-foot FAA limit. That allows a comparison of the virtual model with the actual near-fieldmeasurement, which is, in fact, an unfocused representation of what the radiation characteristics look like in the far-field.
The drone pilot then collects the data and returns it to Dielectric, where engineers export and plot the data over the virtual model. Once compared and confirmed, a report is provided to the end customer, which is typically a TV station engineer or a consultant representing the broadcaster.
“The ability to compare near-field measurements with the virtual antenna model confirms that measurements in the far field would return the same data but, just to be sure, we carried out far-field drone measurements as well. The results matched,” said Nicole Starrett, Electrical Engineer, Dielectric. “The added benefit is that the antenna characteristics can be quickly transformed to any distance, near or far, for comparison. ”
Starrett adds that Dielectric has the ability to model any antenna for which they have detailed drawings and data, which means the service will most likely be restricted to Dielectric antennas. “Dielectric had more than 80 percent of the repack business in the USA over the past three years,” said Schadler. “That takes our total number of repack antennas shipped to 948, so we expect to be quite busy supporting this new service.”
Starrett will present Near Field Drone Measurements of Broadcast Antennas at 10:45am on Thursday, October 15 at the Wisconsin Broadcasters Fall virtual event, as well as virtually at the Radio Club of America Technical Symposium on Friday November 20th.

MSolutions Updates IP Network Analyzer Software to Test AV over IP Performance with NETGEAR Switches
Upgrade also adds new analysis and monitoring features compatible with three series of NETGEAR managed switches
RA’ANANA, ISRAEL, September 8, 2020 — MSolutions, a leading supplier of test devices for commercial and residential AV environments, today announced that its IP Network Analyzer software is now compatible with NETGEAR managed switches for more comprehensive, in-field testing of AV over IP networks. NETGEAR becomes the second industry-leading network switch brand to be supported by the software, following last month’s initial release with Cisco switch compatibility.
MSolutions has also added two new IP Network Analyzer software features—Port Connected Status and Real-time Bandwidth Monitor—which expand its testing functionality for NETGEAR and Cisco switches. Port Connected Status letsinstallers identify the number of ports the switch has and which ones are physically connected to the network, while the Real-time Bandwidth Monitor enables them to assess the bandwidth being used by a particular port in near real time.
The IP Network Analyzer software runs on MSolutions’ portable MS-TestPro testing device, which is the first HDBaseT tester to integrate AV over IP analysis capabilities. When connected to a compatible network switch, the IP Network Analyzer software uses vendor-specific parameters to perform custom testing and reporting that help installers fully evaluate the integrity and performance of AV signals transmitted over the IP network. The MS-TestPro is immediately compatible with NETGEAR’s M4200, M4300 and M4500 Series managed switches.
The data and analytics generated by the IP Network Analyzer software let installers immediately verify if an IP network’s settings and cabling satisfy the desired performance and resolution requirements. They can also determine whether a switch is properly connected and configured on the network to enable uninterrupted video streaming.
“As more businesses transition their AV systems to IP networks, end users need the confidence that their networks are secure, highly available, and optimized for performance as video, audio and data traffic move through the facility or campus,” said Laurent Masia, Director of Product Line Management, NETGEAR. “As NETGEAR managed switches lie at the core of these systems, our customers depend on their reliability across all of these areas. MSolutions is providing integrators and tech managers with the exact toolset they need to test, verify, troubleshoot and certify that reliability and performance within and AV over IP environment.”
In addition to the new Port Connected Status and Real-time Bandwidth Monitor functions, other key IP Network Analyzer software features include:
- Identification of network configuration faults
- Identification of network port status (open or blocked) and present network nodes
- Confirmation that pertinent multicast settings are correctly enabled
- IGMP Snooping, including VLAN setup and fast-leave supports
- SNMP compatibility for network status queries
“Our MS-TestPro with the IP Network Analyzer software enables AV installers and systems integrators to perform critical testing while they’re in the process of deploying an AV over IP network,” said CEO Eliran Toren. “Our integration of HDBaseT, HDMI and IP network testing in a single device further bolsters our ‘all-in-one’ value proposition, sparing technicians from the need for multiple, stand-alone test devices while easily addressing hybrid installations in both commercial and residential installations. We are excited to add support for NETGEAR’s popular managed switches to our constantly growing list of compatible vendors.”
Customers can download the updated IP Network Analyzer software to their existing MS-TestPro devices for a free 14-day trial or purchase it for use on new devices. Compatibility announcements with network switches from additional leading manufacturers are also expected over the coming months.
Since 2016, MSolutions has developed state-of-the-art HDBaseT test, multimedia and switching solutions for leading enterprises and integrators in the Pro AV and government markets. The company designs and manufactures advanced, high-quality systems that make media networks based on HDBaseT easier to install, more stable, and more enjoyable for end users.
