Since on-water communication is critical to boater safety, VHF radio and antenna checks should be performed not only at the start of the season, but prior to every trip on the water. The ART-3 Antenna/Radio Tester from Shakespeare Electronic Products Group is a quick and simple way to measure VHF radio and antenna system performance.

Unlike calling for a radio check, testing can be completed by one person with the pocket-size ART-3. It measures radio output power, antenna VSWR (efficiency), and receiver functionality using simple switches and a dial knob. The sturdy die-cast aluminum device displays RF output power up to 30 watts on an easy-to-read, built-in scale.

It can be connected to the onboard 12V DC power supply with an included power cable, or run off its internal battery. The ART-3’s battery level and the ship’s 12V DC power level can even be checked through a switch on the unit itself.

The suggested retail price of the ART-3 Antenna/Radio Tester from Shakespeare Electronic Products Group is $144.95.
