SPINNER Antenna Monitoring System:
Stay on Air!

The SPINNER Antenna Monitoring System - AMS is engineered to detect arcing and water ingress in broadcast transmission systems at an early stage and alert you to problems before major damage can occur. It helps you stay on air.

Radio and television broadcasters rely on their systems to deliver content to subscribers. Though the infrastructure is robust, it is not failure-free. The insulation of cables and dipole antennas can become brittle and crack from prolonged exposure to UV radiation. Feeder cables can be damaged by strong winds, ice or corrosion. Problems can also result from improper installation or RF overloads.

In the long term, these problems can cause the site to be off-air through degraded RF-components or even lead to fire, completely disabling the broadcast system. Operators therefore need a system that reliably detects and pinpoints problems before they can lead to more serious damage. The SPINNER Antenna Monitoring System does all this and more.


SPINNER Broadcast AMS Cost

Off-air time isn't just a technical issue. The financial cost of repairs and claims brought by content providers can also be huge. By helping you avoid these pitfalls, the AMS gives you enormous value for money.

This SPINNER solution monitors the entire antenna system, including patch panels, feeder cables and dipoles. New, recently patented measurement methods reliably detect even minimal arcing and compromised insulation in antennas of any height.

All events are continuously recorded and can be checked from anywhere via a user-friendly web interface. If arcing is detected, the AMS triggers an alarm locally on LED lamps and remotely via an SNMP interface. The transmitter can be optionally connected via an interlock interface that cuts off or reduces the power to protect equipment.

SPINNER AMSSPINNER Antenna Monitoring System

All components are indoors with fast and easy installation, also in existing sites. The AMS is available in two different versions for FM, VHF and UHF.

AMS U-Links

To ensure fast and easy installation and minimally invasive changes to existing systems, we have integrated the AMS detector in U-links for mounting on any SPINNER patch panel.


AMS U-links are available in the following sizes: 1 5/8”, 29-68, 43-98 and 52-120.
