em-trak Zero-Loss VHF Antenna Splitter, IPx7

The em-trak VHF Antenna Splitter is a zero-loss splitter rated IPx6 and IPx7, letting an AIS receiver and a VHF radio share one antenna.

Zero-loss is the specification that matters. A passive splitter divides signal strength between outputs, weakening both, and on a VHF that is a direct reduction in the range at which a distress call is heard. An active zero-loss design amplifies to compensate, so neither the radio nor the AIS loses performance.

Sharing one antenna avoids a second mast fitting and a second cable run, which on a sailing boat means no additional weight or windage aloft. IPx7 covers immersion rather than just spray, which is the right rating for equipment that may sit in a locker that floods. Explore more marine antennas.

• Zero-loss, so neither VHF nor AIS is weakened
• A passive splitter cuts distress call range
• One antenna instead of two aloft
• IPx7 rated for immersion, not just spray
