Beacon "NC" Antenna
The antenna is a single #14 solid copper wire approximately 45 feet in length. Not the best for the job but cheap if you buy 14/2 with ground house wire and strip the wires from the sheath. The vertical wire extending from the coil to a support line (weed eater line) tied from a tower to a tree. At the top of this wire there are six 25 foot long drooping top hat wires. These wires are tied to the building corners with......you guessed it......, weed eater line. This picture was taken from the ground looking up. The dark spots are light weight plastic insulators. I have found most weed eater line to be a good high voltage RF insulator but not all of it is.
