SWR is just always low. Tunes your coax fed or random wire antennas 1.8-30 MHz from 2 Watts QRP to full 200 Watts SSB/CW.
Matches 6-1600 Ohms (SWR up to 32:1) -- thats a 50% wider matching range than competing products that are less capable and higher priced. And its made in the USA. As youre ragchewing, contesting or DXing, the MFJ-939 is learning your antenna and the way you operate and storing all this in its 20,000 memories. The more you use it, the more it learns.
Measure & Compute = Instant Match MFJ-939 uniquely measures your antennas complex impedance (R, X), computes the L-network and snaps in needed components for instant matching. AdaptiveSearch determines a sub-set of all solutions that can provide a safe match and searches only that subset giving you an ultra fast match.Others search slowly through all solutions. InstantRecall first checks its memory to see if you have operated this frequency before. If so, tuning is instantaneous and youre ready to go! MFJ exclusive VirtualAntenna Memory system gives you 8 antenna memory banks of 2500 memories each. You can use an antenna switch to select up to 8 antennas and assign each antenna its own 2500 memories! 4 Times More Solutions and Faster! MFJ has 256 values each of capacitance and inductance for 131,072 matching solutions giving you a finely tuned very low SWR. That`s 4 times the 32,768 solutions of competitors using only 128 L/C values each!
Don`t be fooled by competing products claiming fast search times -- if you have a quarter of the matching solutions, of course, it takes less time to finish but it's not faster. MFJ`s faster speed comes from advanced technology and software algorithms not from fewer solutions. An Audio SWR meter beeps when SWR <1.5, 2, 2.5, 3.
