Omnidirectional high gain antenna

1. Product overview: This antenna is a portable ultra short wave broadband omnidirectional antenna covering the frequency range of 30MHz to 3GHz, which can be used for transmitting, detecting, and measuring electromagnetic wave signals in this frequency band. The antenna utilizes the inherent non frequency variation characteristics of the disk cone structure, ensuring good impedance matching throughout the entire frequency range, and can be directly connected to the receiving device without the need for tuning devices. The antenna adopts an umbrella shaped folding structure design, with a flexible telescopic mechanism that can be quickly unfolded and retracted. It is small in size, lightweight, and convenient to carry. Applied to the reception of radio signals in fields such as spectrum monitoring and electronic reconnaissance 2. Main technical parameters: Frequency：30MHz～3000MHz; VSWR：≤2.5; Gain: 0dBi (typical value) Polarization: vertical polar…
