1. Here is the prototype Monarch capacitor (with reduction drive attached), built by Chuck W6FT, using 7 sets of 3 inch Monarch plates. Two #8 nuts are used to space the plates on the 8-32 threaded rod rotor shaft. The stator plates are assembled on 6-32 threaded rod and also spaced by two #8 nuts. 8-32 tapped ¼" aluminum tubing is threaded onto the end of the rotor shaft. The measured spacing between rotor and stator plates is 0.1". |
 |
2. The 1.6 L Really Useful Box is drilled. Two SO-239 connectors are mounted with 6-32 screws and nuts. Two ½ inch PVC conduit clamps are mounted on the bottom of the enclosure with #10 hardware. |
 |
3. A large hole is drilled in the opposite end of the enclosure to accommodate the round brass plate of the reduction drive and the ends of the two 6-32 screws are secured to the box with #6 nuts. (The angle bracket has been removed from capacitor and was not used). |
|
4. Two 2 inch lengths of 10 AWG stranded wire are tinned and a #6 ring terminal soldered to one end of each. |
|
|
5. The SO-239 connectors are removed from the enclosure, one side of each shell is prepped and tinned, and the tinned wire soldered to it using a 100 watt soldering gun as shown. The center pin of each SO-239 is left unconnected. |
|
6. One lead with an SO-239 connector is attached to each stator section of the capacitor. No electrical connection is made to the rotor plates. |
|
7. The connected parts are mounted inside the enclosure. Both leads of the NE-2 neon glow lamp are attached together to the same stator section (the high radio frequency voltage present there at resonance is sufficient to make the neon lamp glow with no other connection). |
|
8. The antenna is tuned with a vinyl Mini Blind Wand that is secured to the reduction drive shaft with a small hose clamp. Do not touch the bare metal shaft during transmission as any imbalance in the loop may place dangerously high radio frequency voltage on the shaft. *Adjust the capacitor only with clockwise rotation to avoid loosening the tapped aluminum tube from the threaded shaft. |
