Isotron 225 AM Antenna

Isotron 225 AM Antenna is a compact factory-tuned AM broadcast antenna for mid-band AM transmission with no grounding system required.

Product overview

The Isotron 225 AM Antenna is a compact AM broadcast antenna designed for broadcasters who need a space-saving alternative to conventional AM radiator systems. Source material identifies the ISO-225 model as covering approximately 1.350 MHz to 1.590 MHz, making it suitable for mid-band AM broadcast use. The antenna is factory tuned to the ordered frequency and requires only minor assembly and adjustment by the customer. It fits naturally with AM transmitters and is well suited to specialist installations where limited space or simplified site work makes a compact antenna attractive.

Connectivity and construction

The Isotron 225 AM Antenna is part of the Isotron AM broadcast range, which Progressive Concepts describes as covering the AM broadcast band with different models selected by frequency. The 225 model is listed with an approximate maximum length of 233 inches, approximate weight of 11 lbs, an SO-239 connector and no requirement for a grounding system.

In operation

In daily use, the Isotron 225 AM Antenna is intended for low-power to medium-power AM broadcast projects where a conventional full-size grounded radiator is not practical. Its compact physical format and simpler installation make it attractive for restricted-space sites, technical experiments and specialist AM services. Because the antenna is built to order for a defined part of the band, it is best specified carefully at purchase to match the intended operating frequency.
