I am building a multi band vertical antenna using aluminum tubing. I need to build a loading coil to compensate for the short section of tubing I am using. I am using 10 gage aluminum wire to make the coil, but since it is not covered, I need to create a small space to separate the turns. The coil form is 1 inch OD hi density plastic. I am thinking that the correct size threading die should work, but not sure what size or pitch should be used. If any one has a suggestion or has done this before, I'd appreciate any information available. 73 Bill KL7YB |
