Why did you give up before it was properly tuned?


Sold my antenna support, 3 story house.


The matching section for your 20m 1/2WL monopole can
be mounted horizontal if it is more convenient. FP
is where it connects to the 1/2WL vertical section.

+-----------X-----------16.5'---------------+FP

+-----------Y-----------16.5'----------------open

The coax connects at X and Y where the 50 ohm feedpoint
is located. #14 or larger wire will handle anything
legal that you can put into it. No high voltage capacitors
required. No lossy coils required.


Thanks Cecil This was my first plan but I dont have room to run the stub
straight out so I kind of tabled the idea for a while. Now that I have
thought about it there is no reason I couldnt wrap it around the antenna.
Talking with others sure helps the thought process. I still may play with
the idea of the 20M Ringo design. It would be a lot of fun telling people
you have a 20M Ringo Ranger. My only real problem with using the Ringo style
matching network is that I heard once upon a time that the Ringo utilizes
the mast as part of the radiator. The main thing I see the Ringo type match
has going for it is that it would be about half the size of a 16.5 ft stub
wrapped around the antenna
