Hardware Used During Repairs

This isn’t a very exciting page, but I wanted to keep notes on exactly which parts were used during various repairs of the antenna system.

Tower

Replaced the original winch with a Fulton 2550 winch, which is what US Tower now uses by default.  US Tower quoted me over $600 for this, but I bought it at E-Trailer.com for about $150.  The mounting holes are identical to the original K-1500 winch so it is an easy replacement.

Nuts/bolts to secure the winches (both of them) to the tower and raising fixture:

• 3/8-16 x 1″ stainless steel bolts: McMaster Carr 92240A624
• 3/8-16 nylon insert stainless steel nuts: McMaster Carr 91831A127

US Tower thrust bearing grease fitting: McMaster Carr 1293K47

Force 12 C3S beam

Elements:

Aluminum blind rivets, 1/8″ diameter for  .1″ material thickness.  McMaster Carr 97447A015

Element tips: 0.375″ tubing (DXEngineering.com) purchased in 6′ lengths.

• 20 meter driven element: 40″.  Telescope so 35.25″ inches remain.
• 20 meter reflector: 41″.  Telescope so 36.25″ remain.

Boom to Mast Plate

• 2 Inch U-bolts to secure plate to 2″ mast: McMaster Carr 3042T161
• 2-3/16 U-Bolt to secure plate to boom: McMaster Carr 3042T55
