4527, Panel-Mount RF Wattmeter
Bird's 4527 Dual Meter, Dual Element Panel Wattmeter with Sampler Port is tailored for 2-way mobile applications in the 2-512 MHz range. The panel is configured with dual meters and element sockets. These features let you determine VSWR more precisely using a more sensitive reflected power element and simultaneously read forward and reflected power.
In addition, an variable RF probe provides a low power sample of the signal being measured and is available at a female BNC connector on the front panel, along with a control knob for adjustment. Note: The 4527 uses 2 to 512 MHz Plug-In Elements from Tables 1, 2 and 6
