Does any body know how to build an antenna Matcher for CB radio that can explain or have picture I want to build a small simple one using trimmer pots / air caps?
This simple tapped L match works well for me. The input from the radio is at the coil end, the output to the antenna is alongside the capacitor.
I made a coaxial vertical dipole, cut for 11 meters, fed with 50 ohm RG-213. The antenna doesn't present a 1.1 swr match, so I built the tuner to match the antenna to the radio.
Hi dc2rf i have a half wave dipole that has a swr 1.5. whilw it is not bad, iwould like to bring it down to a 1:1 match.
I have one of these and it is a great and quick way to reduce your swr readings. This meter is the easiest to use and it is quick.There is an easier way than building one for yourself; but perhaps not as satisfying as building your own.
MFJ makes the MFJ-949 tuner that can be had for as cheap as $50/used and will work right now. It also has a built-in cross-needle SWR meter - which is the best way to have an SWR meter - IMO.

Have a parts list and schematic?I know this post is a bit old but I couldn't resist-----I through this together on about 5 minutes and will match anything--even a old rusty steel fence post.
Link coupled tuner is the way too go.
