CX 160 U VHF Base Antenna, 160-164 MHz

Further details of CX 160 U VHF Base Antenna, 160-164 MHz

The Sirio CX 160 U is a VHF base station antenna designed for use in the 160-164 MHz frequency range. The antenna features a 3/4-wavelength coaxial J-Pole design and is constructed from aluminum tubes and nylon elements. The Gamma Match feed system provides a grounded design to protect against static discharge. No tuning is required within the specified frequency range.
