Slipp-Nott System
The Slipp-Nott system was developed by Roger Greenfield (WB8NDC) in an effort to resolve the problem of large arrays slipping on masts, which not only presents an annoyance but can cause catastrophic failure in mechanical and feedline assemblies, leading to costly tower work and repairs.
The Slipp-Nott replaces the traditional U-bolts that are common with most antenna mounting systems.
This innovative design provides an improved boom-to-mast clamp thru the use of wide saddles, resulting in greater contact area for maximum resistance to slippage, especially on smooth and “slippery” 4130 steel masts.
Constructed of a precision fitted and fully welded steel box and saddle for maximum strength, then powder coated for a long service life.
The Slipp-Nott clamp attaches to the thick 1″ PVC insulator, providing 340° of surface contact on 2″OD mast tubing.
It is imperative that a 2″OD mast be used to ensure proper surface contact. Any sizes larger or smaller simply do not align with the ID of the Slipp-Nott saddles and will not provide the maximum benefit.
Once installed onto the booms, the thick PVC serves as an insulator between the booms and the mast, and provides a rigid mount for the Slipp-Nott clamps.
If you have a need for mounting to something other than 2″OD, such as a tower leg, give us a call.
We can custom drill insulators to accommodate any OD or common square U-bolt Dimension.
