Like new condition comes with 2 plug-in elements:
2-30MHZ @100watts and 50-125MHZ @ 25watts and
blank slug to dampen meter movement (for shipping). S/N 9275

The 4413 is an insertion-type RF wattmeter, designed to measure RF
power and load match in 50 ohm coaxial transmission lines. It is
intended for use with CW, AM, FM, and TV modulation, but not pulse
modulation. When used in 50 ohm applications, the 43 has a
maximum VSWR of 1.05 for frequencies 0.45 to 2300 MHz, and

power rated from 1 watt to 10KW . The meter
provides direct readings in watts with an expanded scale for easy
reading. The scale is graduated for 25, 50, and 100 full scale. Elements
are available in a variety of power, and frequency ranges. As you can see
this can also sample RF.
