The tower has a 4° slope on the main lower beams. The base of the tower is approximately 23 feet wide. The first horizontal beam is 8 feet from the ground. The second beam is 7 feet above the first. The supporting angled beams, running from the group, are at an angle of 37° from vertical. The ham shack is located on the south side of the tower with a slight peeked roof. The top of the roof peek is 6 feet from the second beam. The edge of the roof is approximately level with the first beam.
The beams themselves are 3.5in horizontally, 3in vertically, and 0.25in thick with a rounded edge. The double beam which forms the second horizontal beam is 1.25in thick.
All equipment must be mounded on galvanized supports which are themselves attached to the tower using beam clamps. All current mounting brackets should be considered unusable. Mounts using "stacked" struts are no longer allowed.
Cabling must be run with beam camps and stainless steel zip ties and cannot be directly attached to the tower. Cables run into the shack via rubber cable glands (not the plastic tube!). Cable loops are discouraged, as is excessive cable in the shack.
The site provide main power (without backup) as well as 24vdc, 12vdc and -24vdc (breakers not provided) with battery backup. No solar or generator.
Originally we used the provided backup 24vdc power, but switched to our own 200Ah battery (~2 days of power) to avoid negatively impacting the rest of the site's tenants.
The site is own and managed by Matthew Kaufman as part of the WB6ECE Repeater Group.
Coordination of changes to the site (e.g. new radios) is managed on the mailing list Sbruno_shack.
