We do not use eyebolts as antenna connections. The Eyebolts are for BALUN and antenna suspension ONLY.
Stainless Steel or iron eyebolts and some copper antenna wire will oxidize or corrode due to dissimilar metal contact.

We use solid brass terminal posts to enable good RF, electrical, and mechanical connections
between the BALUN terminal posts, and the antenna wire.
Ring terminals are silver plated bronze to prevent oxidation caused by dissimilar metal contact.
We made the antenna screw connection at right angles to make antenna screws easy to tighten
without turning the solid brass terminal. All terminal posts and connectors are installed with tin plated
lock-washers between each metal or case contact surface. By using tin-plated lock-washers, we further
provide better metal to metal contact for better RF transfer of energy to the antenna.

Be sure to seal all terminals with Coax Seal Cat # CS 104. in the Commonwealth of Virginia
