proTAC 5311 Promarine Ltd



  • Network:

    GSM, 4G, 3G

  • Application domain:

    for boats, for ships, for yachts, for sailboats

  • Type:

    vertical, omnidirectional

  • Other characteristics:



High performance GSM/4G/WLAN antenna specially for 4G/LTE routers. Maximizes the 4G/LTE network range and performance. From 690 MHz to 6 GHz and beyond.

ProTAC 5311's efficiency is over 90%, compared to the traditional antenna's best case scenario of 60-80% efficiency!

Traditional cellular antenna has very narrow bandwidth and it only covers either uplink or downlink frequency of operators network. This causes great non-symmetry to link and reduction in throughput (Mbps). Our innovative design makes it possible to extend antennas bandwidth to cover both uplink and downlink frequencies at the same time in all communication bands with the radiation performance over 90% compared to traditional antenna's best case of 60-80% efficiency. The only one in the world!

Advantages of using proTAC™ technology

proTAC™ 5311 maximizes the 4G/LTE network range and performance. They are easy to install, very robust and have accessories that enables drop in replacement installation to existing antenna locations.
