Default inexpensive antenna tuner for 10-12 meters on a sigma 4 ?


what would be a decent AND inexpensive antenna tuner that will allow a sigma 4 to make a decent match for a 2950DX usable frequency range ? power would be about 200 pep .

id also appreciate links to simplified/dummy down info on understanding tuners , how they work and what separates good ones from bad ones ..... if possible .

thanks

If you plan on staying below 300W, look for a Dentron Jr. Monitor tuner.I've seen these at hamfests and swapmeets as lows as $20.The construction is 10X better than a comparable MFJ.

Just a few listed of many there.

for what you are trying to do if you happen to have a couple air variable caps and an enclosure you may be able to homebrew one.

Guts of the 949.

There have been cases in which there is arcing in the variable capacitors.
