Product information

Sirio GP antenna FMGPA 66-108 (500W)

Reliable 1/4 wave base station performance

The FMGPA 66-108 is the ideal choice for broadcasters, base stations and amateur radio operators looking for an indestructible and efficient vertical whip antenna. With a linear gain of 0 dBd (2.14 dBi) and a low beam angle of $0^\circ$ relative to the horizon, this 1/4 wave Ground Plane
delivers a powerful signal over the entire environment. The antenna has a perfect $360^\circ$ omnidirectional radiation in the horizontal plane.

Easy tuning via the length scheme

Thanks to the telescopic elements and the included tuning table, the antenna can be precisely adjusted on location to your desired broadcast frequency. At a resonant frequency, the antenna achieves an extremely low standing wave ratio (SWR) of FMfrequencies (such as the 87.5 - 108 MHz broadcast band).

Built against the elements

Radio masts are exposed to extreme weather conditions. That is why the GPA 66-108 is designed to effortlessly withstand wind gusts of up to 150 km/h. The combination of robust drawn aluminum blades, nylon insulators and stainless steel mounting materials prevents electrolytic corrosion. With a total weight of only 700 grams and a total height of approximately 1.93 meters, the mechanical load on your mast or mounting support is minimal.
