Remote control & connectivity

With built-in Bluetooth, the MRTS-7 Pro can be fully operated from the GMDSS Multi Software on a computer or smartphone. This feature is especially valuable when testing equipment with hard-to-reach connection ports. Simply connect the tester to the equipment using the required cables, pair it with your device over Bluetooth — and you can manage the entire testing process comfortably from the app, with all measurements controlled remotely.

The tester supports signal transmission and reception either through a broadcast antenna or via a direct cable connection.

Universal power sensor covers both VHF and MF/HF measurements and now features a rugged metal connector for added durability.
