Plug &
Play Auto Tuner . . . Plug & Play! You won’t even know it’s there .
. .
The MFJ-939Y automatically tunes your antenna as you tune your
radio. 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) -- that’s a 50% wider matching range
than competing products that are less capable and higher priced . . .
and it’s made in the USA.
-
Highly
intelligent, ultra-fast tuning! As you’re 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 antenna’s
complex impedance (R, X), computes the L-network and snaps in needed
components for instant matching.
-
AdaptiveSearch . . . 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 . . . InstantRecall first checks its memory to see if
you have operated this frequency before. If so, tuning is instantaneous
and you’re ready to go!
-
MFJ
VirtualAntenna Memory . . . 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.

Audio SWR
Meter . . . An Audio SWR meter beeps when SWR <1.5, 2, 2.5, 3.
Alarms if >3. Audible & Visible Diagnostic messages.
-
Heavy-Duty Components . . . Heavy-duty L-network: 10 Amp/1000V
relays, RF duty silver mica caps won’t burn up. Safe, reliable,
continuous 200W SSB/CW.
-
As Small as
Your Radio . . . Tiny 6 1/2W x 2 7/8H x 8 3/8D”. 2.4 lbs. SO-239s,
random wire antenna. & ground posts.

Never
Obsolete!
If you get a new transceiver, simply order a new Plug and Play cable for
that tranceiver.
