 # TFSIK01A - Dual Antenna diversity telemetry modem with a high noise immunity
 
 The TFSIK01A is a high-end open-source hardware design of a UAV modem with [SiK firmware](https://github.com/ThunderFly-aerospace/SiK). It uses the latest Si1000 series chip Si1060 which is equipped with [Si4463 EZRadioPRO Transceiver](https://www.silabs.com/documents/public/data-sheets/Si4463-61-60-C.pdf).
-The RF front is designed to have high immunity to the jamming on out-band frequencies, this gives TFSIK special features such as being operable in the  proximity of out-of-used band signal jammers.  RF noise immunity is a hardware-based feature, therefore it is extremely reliable, but the proper antenna and frequency band must be used for the best results. Contact [ThunderFly s.r.o.](https://www.thunderfly.cz/) to get the support and consultation.

 As you can see the antenna kit contains two asymmetrically mounted antenna. The antenna is tightened in position by SMA connectors. The optimal position depends on your exact setup, but generally, the antennae should be orthogonal to each other due to their "donut" radiation patterns. 
 The whole setup of TFSIK01 with the antenna kit should be mounted on by pair of screws in the holes of the antenna kit.
