The MFJ 251
is a switchable RF Dummy Load. It gives you you five non inductive dummy loads in one box!
Select from 16.6, 25, 50, 100 or 150 Ohms with a front panel switch. MFJ-251 simulates high impedances and low impedances with an SWR of 3:1, 2:1 and 1:1, so you can test and calibrate your watt meters and test SWR accuracy. At 50 Ohms it handles 300 Watts for 30 seconds with an SWR below 1.1:1 to 30 MHz.
Covers DC to 60 MHz. Has SO-239 connector. The used non inductive 50 Ohm carbon resistors and low-loss power relays are exclusively manufactured for MFJ.
