CLR 2 coil.
- Thread starter Staybolt
- Start date
The coil I made is using 14 gauge solid copper wire.12 turns inside diameter of 2 inches.
one side of coil connects to vertical radiating element.
other side connects to ground
tap the coil to give you best vswr.
I installed my coil on the side of the vertical element and soldered a wire to the so 239 then tapped coil for best vswr.
Mine was tapped about 4 or 5 turns down from the vertical element.
the coil presents a DC voltage short to ground so the antenna is still DC grounded but for RF it will lower the resistance to present a good 50 ohm vswr.
Just play with it until you get the best vswr.

it is not in the base,, it is on the outside what made you think all that was inside?
The question that was posted, was pertaining to rebuilding/replacing the original toasted coil.
the original coil didnt like high wattage 300 watts was too much and coil would burn up,,, the change i showed was a way to still be able to use antenna at higher wattages,,,, so i think i answered the question of rebuilding/replacing,,,,,
I think you said how to modify the antenna to handle more power. Not how to rebuild the original coil.
Staybolt, there was a discussion of this very topic some time ago. The CLR 2 had two different coil types that were constructed differently. I believe the PCB coil, was fitted in the Archer/Radio Shack version. The Hy-Gain version, was a small coil of wire, wound on a short piece of PVC pipe. I was searching for the actual turns and tap point of that wire wound coil myself, but the thread didn't have that info. I asked Marconi, who had shown photos of his coil, if he has the turns ratio, but did not get a reply.
This is the thread ai was referring to in my previous post.
HY GAIN CLR 2 Survivor
Was going through a few antenna bases today. Came across all the parts to a Hy Gain CLR 2 MODEL 473 . I thought about rebuilding it with a new matching network. Much to my surprise when i checked the matching coil in the base insulator it was good. I say surprise because most are burnt out or...
