Product Details

Installation Instructions
1) The host connects with antenna (directional antenna or Omni antenna) by six RF feeders (about 3meters long);
2) Identification on each antenna terminal (band parameter identification) must match those on antenna when connected through feeders;
3) Omni antenna should be kept vertical position, the antenna spacing is greater than or equal to 50cm;
4)Six directional antennas should toward the same goal area, the antenna facing region is main shielding area, the side and back shielding range is about 30% of the main shielding area;

5)Both antennas and feeders are waterproof, available to outdoors installation. The host without waterproof function should be installed inside or dry place. Or install the host outside with installation box; Omni antenna installed outside, under the roof no lightning rod needed, an open environment need to install lightning rod. The height of lightning rod should be higher than the Omni-directional antenna.
6) The host embedded with cooling fans. The higher shell temperature is normal after a long time work.
7) The installation height of Omni antenna: suggest installing in half height of shielded building or a higher position than half height.
8) The installation height of directional antenna: suggest installing in periphery of the main shielding area, height similar to the main shielding body, the directional antennas with appropriate angle turn towards the shielding areas.
OEM Customized Service
Frequency spreading can be done for Wi-Fi, GPS, Bluetooth, etc.
Silkscreen OEM service can be offered for five jammers or above.
Neutral jammers can be provided.


Recommended Installation Box
It is recommended elect SMa-0603-type specific installation box

Especially for SMa-818K80 high-power jammer installation, beautiful and durable, to prevent damage, outdoor waterproof (feeder out from the antenna holes on frame, antenna holes sealed by seal head);
The upper layer install the host, the lower layer install the power supply.
