Antennes radio FM à gain élevé

Description

FM radio panel antennas

Broadband Directional Panel , very sturdy construction, made of hot dipped galvanized steel. Suitable for high power radiating systems. All insulators are made of PTFE with stainless steel screws. All metallic parts are electrically grounded offering excellent protection against lightning. When panels are mounted on the four sides of a square tower a circular radiation pattern can be obtained. This is what the largest FM stations use in their setups, usually there are at least 4 such panels on the tower and the number can be much higher (8,12, 16 and more).
