The Isotron 400 AM Antenna is a compact AM broadcast antenna designed for broadcasters who need a space‑saving alternative to full‑size AM radiator systems. Positioned for operation in the lower portion of the AM band, the 400 model is part of the wider Isotron AM antenna family and is factory tuned to the ordered operating frequency. The antenna requires only minor assembly and on‑site adjustment by the customer, making it a practical option where site simplicity, reduced mast height or limited real estate are key considerations. It integrates naturally into a complete transmission chain built around our range of AM transmitters.
The Isotron 400 AM Antenna uses a compact vertical structure that reduces the physical height normally associated with AM antennas while maintaining effective radiation for its intended frequency range. It is fitted with a standard RF connector for straightforward connection to the transmitter output and is engineered for outdoor mounting on a suitable support structure. As part of a wider AM broadcast chain, it can be used alongside dedicated AM audio processors, which are optional components that help define a station’s on‑air “signature sound.”
In everyday use, the Isotron 400 AM Antenna is aimed at AM broadcast projects where a conventional grounded tower is difficult to accommodate because of planning, cost or land‑use constraints. Its compact format and tuned design make it attractive for specialist AM services, technical demonstrations and small‑site installations. As the antenna is built for a specific frequency, specifying the intended channel accurately at the time of order is essential to ensure correct tuning and optimum on‑air performance.
