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.
Cheers

Incoming Region Produces X3 Solar Flare |
May 15, 2024 @ 14:55 UTC |
Another major solar flare, but this time from an active region just beginning to turn into view off the east limb. It is possible that the group responsible is old AR 3654 from the previous rotation. The latest flare, an X2.99 event just peaked at 14:38 UTC (May 15). Stay tuned |
