Discover the revolutionary BIG SIGNAL CQ-270 antenna, the power of two single-band antennas in a single high-performance unit!
Highlighted features of the BIG SIGNAL CQ-270 antenna:
· Double Single-Band in One Antenna: This innovative design combines two real single-band antennas for 144 and 432 MHz into one, ensuring maximum performance on each frequency. You no longer have to compromise signal quality; you'll have the best of both bands!
· Polarization Versatility: Ideal for terrestrial communications in both vertical and horizontal polarization, this antenna is also a versatile choice for repeater installations, beacons, and more.
· Performance in Satellite Communications: Its unique radiation pattern with different high and low lobes in the elevation plane makes it an excellent choice for initiating satellite communications. Additionally, it offers full-duplex operation thanks to its independent feeding for each band.
Advantages of choosing the BIG SIGNAL CQ-270 antenna over a traditional vertical:
- Full-Wavelength Single Bands: With real single bands for 2 meters and 70 centimeters, you'll get maximum performance without compromises.
- Urban Noise Reduction: The closed-loop antenna minimizes QRN and urban noise, improving the reception quality of weak signals.
- Guaranteed Performance: Experience superior performance compared to renowned omnidirectional antennas.
- Full-Duplex Operation: Independent feeding for each band, making it ideal for satellite communications (optionally, you can add a duplexer for a single downlink).
- Signal Stability: Less polarization cross-over influence than a traditional vertical, resulting in less QSB, fading, or signal loss when receiving signals with different polarizations.
- Robust and Maintenance-Free: Its solid construction ensures extreme durability and zero maintenance needs.
- Quick and Easy Installation: Pre-assembled elements allow you to have it ready in less than 5 minutes, with no need for complex adjustments after installation.
