Robust active antenna for GNSS 1575-1606 MHz navigation receivers (GPS, Glonass, Galileo…).

  • Maximum filtering against interfering signals. DC-grounding adds protection towards EMC, static charging and lightning strikes. A and B model available.
Availability: Available on back-order SKU: proTAC-8001

Extremely robust active antennas for GNSS (GPS, Glonass, Galileo…) navigation receivers. They utilize innovative dual quadrature feed technology with up to two stage low noise amplifiers to maximize the rejection of sub-harmonics and L-Band signals.

Advantages (compared to traditional antennas)

  • truly circular response over the entire antenna bandwidth
  • superior rejection of multipath and cross polarized signals
  • maximum filtering against interfering signals
  • mechanical design attenuates signals from low elevation (horizon)


proTAC 8001 is designed specially for use with proGPS series isolated GPS signal splitters. It’s DC-grounding adds protection towards EMC, static charging and lightning strikes while proGPS fully isolated DC feed ensures trouble free use even in aluminum made vessels.

proTAC 8002 is designed to easily replace existing marine GPS antennas in high interference environments. It is DC-floating design enables the use with any GPS receiver and TNC connector fits to most existing antenna cables.

A-models have have high quality low noise amplifiers and bandpass filtering in addition to mechanical filtering against low elevation (near horizon) signals like marine VHF, harmonics etc.

B-models have in addition to A-model features a special two stage low noise amplifier and band bass filtering design in order to further attenuate all unwanted signals.
