Dual-Purpose, Lightweight, and Professional FM Antenna Solution

The LOG FM Demountable Yagi Antenna is a lightweight and cost-effective solution designed for low-power FM broadcast applications across the full FM band (87.5–108 MHz). It can be used both as an FM transmitter antenna and as an FM radio receiving antenna, offering unmatched flexibility.

Constructed from non-corrosive aluminum alloy and featuring a 4-element directional design, it ensures reliable performance and long service life. Its demountable structure makes transport and handling easy, especially for mobile FM broadcast measurement tasks and vehicle-mounted installations. The detachable design also reduces shipping costs, lowering the overall purchase expense.

When used as a receiving antenna, its high gain enables superior reception in areas with weak FM signals. This makes it particularly valuable in professional rebroadcasting applications, such as tunnels: the antenna receives FM broadcasts outside and redistributes them inside the tunnel via leaky cable, ensuring uninterrupted listening.

The standard mounting bracket allows installation in both horizontal and vertical polarization, providing flexible deployment options for different broadcast and measurement requirements.
