Alright, now that we’ve covered why this tuner is a gem for both newcomers and seasoned pros, let’s get into the nitty-gritty. First off, the MFJ-993B is a dual power auto tuner that operates between 1.8-30 MHz. It comes with a price tag of $329.95 USD as of November 2023, which, let’s be honest, isn’t too shabby for what you’re getting.

POWER AND IMPEDANCE

Now, let’s talk about power. The tuner has two settings: 300 Watts (6-1600 Ohms) and 150 Watts (6-3200 Ohms).

Ah, the features! The MFJ-993B is an IntelliTuner, which means it automatically tunes unbalanced and balanced antennas. And it does it ultra-fast, thanks to its 20,000 memories.

CONNECTORS GALORE

Now, let’s talk connectors, because this tuner is loaded with them:

  1. Two SO-239 Unbalanced Coax Antenna Connectors: These are your standard connectors for most antennas. Handy for quick swaps or for running multiple antennas.
  2. Random Wire or Single Wire Antenna Connector: If you’re into experimenting with wire antennas, this one’s for you.
  3. Built-in 4:1 Current Balun for Balanced Line Antennas: This is a big deal if you’re using balanced line antennas. It’s built right in, so there is no need for external gadgets.
  4. Optional Radio Interface for Compatible Radios: This is an add-on, but it’s a good one if you want to integrate the tuner with your radio seamlessly.
  5. 9-Pin to 9-Pin Computer Cable for Remote Operation: This allows you to operate the tuner at a distance using the MFJ-993RC. Imagine being able to tweak your settings from the comfort of your chair, without having to dash over to the tuner every time. It’s convenience at its best!
  6. 12V DC Connector: The unit requires less than 1 amp of 12V DC power for operation. Pretty standard, but essential.
