| Building A Loading Coil for Vertical Antenna | KL7YB | on 16/6/21 |
| 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 |

| Can anyone recommend a source for replacement parts for the SB 200? I need a 1000 pF tubular ceramic 5 kv "door knob" capacitor and a .001 uF 3 kv disc ceramic capacitor. Also need to replace the two parasitic plate chokes; probably could build my own around a couple of 50 ohm3 watt carbon resistors. Any suggestions for source of caps will be greatly appreciated. 73 Bill KL7YB |
