Your cart is empty.The MFJ-884 is a compact SWR/Wattmeter designed for HF, VHF, and UHF frequencies, covering a range from 1.8 to 525 MHz. It features a cross-needle meter that simultaneously displays forward and reflected power, as well as Standing Wave Ratio (SWR). Key specifications include: Power Handling: Capable of measuring power levels up to 200 Watts across three selectable ranges: 2W, 20W, and 200W. Frequency Coverage: Operates across the 1.8 to 525 MHz spectrum, accommodating a wide range of amateur device bands. Peak and Average Power Measurement: Allows users to switch between peak and average power readings for more accurate assessments of signal strength. Dual Power Sensors: Equipped with separate power sensors for HF and VHF/UHF bands, each featuring SO-239 connectors for secure and reliable connections. Power Requirements: Operates on 12 VDC or 110 VAC (with optional adapter MFJ-1312D), providing flexibility for various operating environments. Physical Dimensions: Measures 5.5 inches (width) x 3.125 inches (height) x 5 inches (depth), making it a compact and portable solution for field operations and limited spaces. The MFJ-884 is an excellent choice for amateur device operators seeking a versatile and reliable instrument to monitor and adjust their transmission parameters across multiple frequency bands.

just a heads up to help you save time, trouble, and money... although buying a warehouse item can sometimes be a bargain you can run across problems with used gearthis is the second used MFJ wattmeter i have purchased here... the first was returned, and although advertised as working, had a cold solder joint off the internal battery circuit that prevented running without external DC power - a quick touchup with a pen fixed thatthis wattmeter however, arrived rattling in the box which did not bode well... upon opening the package, it was apparent that whoever returned this item performed a parts-stripper, sleight-of-hand to swap a new working unit for an old wattmeter...here's how it works: a LID has a wattmeter for 20+ years and decides to tinker with it and in the process, destroys one of the UHF connectors on the rear of the meter; additionally, when attempting a repair, desolders the connections and forgets how to properly reorient the circuit (MFJ is no help, as the 'manual' has no described circuit - just so you know); the result is a vintage, non-working wattmeter...but then the LID decides to cheat and steal, and upon realizing that the wattmeter is still in production, orders a brand-new one, then subsequently reports it as non-functional and performs a return... only the returned unit is the horked, mangled, and kludged boat anchori am posting this review to help others here who may think they are getting a bargain - sometimes it works, but sometimes it doesn't... this is the third or fourth time i have run across this problem with orders...fortunately, returns are fast and easy, but i am disappointed that LIDS would do this to fellow hams

When working with QRP ( This meter has three ranges: 2 watt, 20 watt, and 200 watt, all selectable with a switch set at x1, x10, or x100. The meter's scale for output power is calibrated from 0 to 2 watts, so it is very easy to read output power down into the low milliwatt range. That feature alone may be worth the price. However, this is a cross-needle meter so it measures reflected power at the same time it is measuring output power, which I find very handy when tuning up my radio and antenna for normal operations. I've had Power/SWR digital meters before, but for shear speed in tuning, I'll take a cross-needle meter for accurately setting the optimal match. But there's more! On the back there are two sets of SO239 input/output connectors. One set for HF and the other for VHF/UHF.So wrapping it all up, you have one meter that accurately measures low power QRP range radios, typical off the shelf HF 100/200 watt range radios, and VHF/UHF radios and handy-talkies.
