Mast Bases

LPI supplies a mast base welded directly onto the required length of aluminium
mast.

Mast Couplings and Guying Points

There are two methods of coupling two sections of mast:
1. The U-Bolt set uses two stainless steel U-Bolts to clamp the two masts
together Figure 36
2. The inline coupling fixes the upper and lower mast sections together and
provides guying points and an exit point for the HVSC Plus downconductor
U-Bolts and inline couplings nuts must be tightened to no more than
55 kg/cm (45 in/lb).
A guying ring is supplied for guy points for any two piece masts that require double
guying. This fits on the terminals mast butt adaptor between the Stormaster ESE
terminal and the top of the mast. See Figure 37.
