Channel Antennas - - Thiết bị tự động hóa công nghiệp - ANS Vietnam

Channels antennas are used for signal reception from one or more channels. It is used primarily in areas with highly saturated frequency band, the frequencies near the desired signal are not disturbed.

In addition to the lower antennas we also produce antennas for other channels:

antennas with two elements: 
VF-2 A (Ch. A)*
VF-2 K4 (Ch. 4)
B-2 B (Ch. B)*

antennas with three elements:
B-3 A (Ch. A)*
B-3 B (k Ch. B)*
B-3 C (Ch. C)*
VF-3 K1-3 ( Ch. 1-3)
VF-3 K4 (Ch. 4)

antenna with four elements: 
B-4 A (Ch. A)*

antennas with six elements:
F-6 FE (Ch. E)*
VF-6 FF (Ch. F)*
VF-6 FH ( Ch. H)*

* antenna with "F" female connector
