North is straight up.
Yellow lines = Beverage antennas
580ft NE (Europe)
500ft NW (Asia)
650ft E (USA and Caribbean) extends off the photo for another 150ft or so
Red line is the 160M half wave sloper
Orange line is the 80M half wave sloper
The tower and shack (grey roof) is on top of a 130ft hill. The shack is about 40ft higher than the roofs of the two story duplexes next door.

The pine tree just to the left of center is the end support of the 160M half wave sloper. It is about 60ft high, and is located about 2/3rds down the hill. The photo doesn't do a justice, but the road is 110ft below the hilltop where I took the picture.
The wire is part of the NE Beverage where it crosses the driveway.

This merged photo gives a better sense of the slope on the north face of the hill. The end of the 160M antenna can be seen at the top of the tree, and you can just make out my car parked at the shack atop the hill. The NE and NW Beverages both diagnal their way down this slope to their terminations.

I took this picture standing at the base of the pine tree, showing the plane of the 160M half-wave sloper toward the tower. The antenna is tied off @ ~130ft on the tower itself, about 180-190ft above the point where I am standing (the other end is terminated 60ft above my head)

This is the path toward Europe, standing under the 160M antenna. The ground drops off dramatically in this direction, dropping 130ft to sea level in less than 100 yards. Salt water is about 1/3 mile away. The 80M antenna "sees" just about the same thing. The TH7 tribander is fixed @ 70 degrees for domestic contests.

This is the feedpoint of the NE Beverage. The jug is protecting the 6.25:1 isolation transfer (75 to 450 ohm) of W8JI design. Both sides of the transformer are grounded independently to reduce the chance of common-mode currents as per W8JI advice. The ground rods are 4 ft long, three total (the secondary is grounded to two daisy-chained rods, the second one not shown)

The feedpoint end of the NE Beverage. The ends aren't sloped (again, W8JI advice: 8ft of drop is 8ft whether vertical or sloped 50ft). This antenna is 580ft long @ 40 degrees, just south of short path to EU. It is fed with 50ft of RG11 where it transitions to 7/8" CATV hardline to the shack. The transition is once again grounded to reduce common-mode currents in the feedline.

This is the crossing point of the NE and NW Beverages (NW on top) at the crest of the hill. Both antennas are fed on the back side of the hill, crest the peak, and are terminated at the bottom of the hill in their respective directions. The wires are between 7-8ft high except where they cross the driveway. They are made of standard #14 insulated stranded copper wire.

This is the NW Beverage termination. All antennas are terminated with five 2.2K ohm resistors in parallel (440 ohms, measured value more like 450). Each antenna has two 4ft ground rods.
