SkyLink® DP

4 x 4 MIMO Omnidirectional Airborne Antenna

This popular deployable data link system extends a mast below the aircraft skids to allow omni-directional antennas to operate below the skids eliminating interference or being blocked by external payloads: camera gimbals, floats, steps, skids and other aircraft mounted equipment.

Optional Dual-Polarized Omnidirectional Antennas
Designed to operate in two frequencies simultaneously and supports bidirectional Multiple Input, Multiple Output MIMO.

Troll’s horizontal and vertical dual polarizations in a single lightweight aircraft rated package is available in S and C bands. By providing orthogonal RF paths the dual-stream capability Troll antennas maximize MIMO radio performance. Dual-stream systems can provide higher bitrate or increased redundancy to optimize range or throughput. Troll’s dual-polarized omni antennas are also suitable for many wireless radio waveforms.

Troll omnidirectional antennas support 1×2, 2×2 and 4×4 channel MIMO systems.  They also support a wide variety of OFDM wireless protocols: like 802.11, WiMAX, Wi-Fi to provide broadband networking, long distance point-to-point links to mobile cellular access.

The SkyLink® DP utilizes a pilot panel onboard the aircraft to deploy and retract the antenna safely. Additionally, an easily broken, frangible link design protects the aircraft if it accidentally lands while the antennas are deployed.
