We are professional manufactures and exclusively dedicated to full wavelength antennas like Cubical Quad and Delta Loop. Steady developing and innovating of new designs we currently can count more than 50 references in our catalog and offer antenna solutions for any use or frequency:
- HF, VHF/UHF, CB (27 MHz)
- Balun and Unun devices
- Installation accessories
Why choose BIG SIGNAL?
Less QRN, better reception
The design of Quad antennas causes attenuation of the QRN/QRM that we unfortunately suffer more and more in urban environments. The decrease of this effect, will allow us to hear weak signals that with other types of antennas we could´t relocate.
Very low radiation angle
The Quad antennas have a very low radiation angle even at low altitude, which is crucial for the DX.Therefore these will always be more effective at less height than other types of antennas.
Electrically there is no possible discussion, a full wavelength increases about 1.5 dB than a half wave dipole (Yagi).
Excellent lateral rejection
The front / side relation of the Quad antennas is exceptional, providing high directionality and at the same time reducing the noise of the rejection directions.
Ideal for small spaces
Our multiband Quad antenna with 2 elements and 5 bands with only 2,84 meters of boom and its small turning radius is the perfect solution for limited spaces. It guarantees superior performance compared to other Full-element antennas with thesize of more than 10 meters in width and superior length of boom. No other HF antenna offers similar performance in such a small space!
Because of its manufacture, its weight is reduced considerably compared to other aluminum antennas of similar characteristics.
