Common Concerns Answered
What if I need to test antennas outside the 155-158 MHz range?
The ART-3 is specifically engineered for standard VHF marine frequencies. While its dedicated range ensures precise testing for those bands, users requiring broader spectrum analysis may consider alternative analyzers with extended frequency coverage.
Do I need extra cables for this tester?
The ART-3 utilizes standard SO-239 connectors. For certain VHF radio models, an optional Style 4079 cable may be required to complete the connection between the radio and the tester.
Is the ART-3 difficult to operate on a boat?
No, installation is not required. The ART-3 is a portable diagnostic tool designed for immediate use, connecting directly to your antenna and radio system for quick testing.
Frequently Asked Questions
What specific tests can the Shakespeare ART-3 Antenna Radio Tester perform?
The Shakespeare ART-3 performs three critical tests: receiver function, output power, and VSWR (Voltage Standing Wave Ratio).
How is the Shakespeare ART-3 powered?
The ART-3 is versatile in its power options, operating via its internal battery or directly from your vessel's 12 VDC ship power system.
What is the operational frequency range of the Shakespeare ART-3?
The ART-3 is designed to operate within the 155-158 MHz frequency range, which covers standard marine VHF communications.
Can the Shakespeare ART-3 evaluate the receiver's performance?
Yes, a key distinguishing feature of the ART-3 is its capability to test the receiver function of your VHF radio system, alongside output power and VSWR.
What is VSWR, and how does the ART-3 measure it?
VSWR, or Voltage Standing Wave Ratio, indicates the impedance match between your radio and antenna. High VSWR can reduce transmission efficiency and potentially damage your radio. The ART-3 measures this parameter directly.
