Antenna Tuner For Your Ham Radio Shack

Right now I have two different antenna tuners for my ham shack. I have an MFJ-949E Antenna tuner. This is a manual antenna tuner. It will tune it will tune dipoles, inverted v antennas, beams, verticals, mobile whip antennas, scanner antennas and shortwave antennas. I use it with my 10 to 80 meter dipole antenna. It does a pretty good job at tuning to a low swr reading. The only drawback I have found with it is that the knobs are not very comfortable and after awhile your fingers get sore. As far as tuning goes I wrote down the various settings for different frequencies. I keep a chart handy so I can easily tune to the frequency I am on using my Kenwood TS-2000 Ham Radio. I have tuned frequencies from about 1.8mhz to 30mhz. I would recommend it to anyone as a manual tuner if you are running np more than 300 watts.
  My other antenna tuner is a MFJ 993b automatic antenna tuner. It pretty much covers the same Ham Frequencies as the MFJ 949E antenna tuner. It does take a little getting used to with all the different settings and button choices. However once it is set up it works like a charm. It does only go up to 300 watts so do not go higher than that. The only problem that I ran into was with the on off power button. It last somewhere between 3 months to a year and then it has to be replaced. I had replaced it with switches from MFJ quite a few times and decided to do something different. I replaced the on off switch with a good toggle switch. I wrote about this in an earlier post. I have no had any more problems with the switch since then. This is my main antenna tuner at this time.
  There are quite a few good antenna tuners made by MFJ despite the varying reviews I have read. There are other brands of antenna tuners that have caught my eye. Some of those brands are Palstar, Ameritron, Vectronics and LDG Electronics. I really like the Palstar Antenna Tuners, but they are out of my budget at this time. I do have to say the reviews are very good and they look like they are built like tank. I also like the high end automatic tuner in the LDG Electronics line. I read the reviews and they seem to be pretty good. For myself I am not running an amplifier at this time and have no need for one. Maybe one day in the future I will be looking more at one of them. Also most Base Ham Radios have an antenna tuner built in them that usually is good up to 100watts.
