3 Section Mast 10.5m

This mast has been developed for light to medium UHF, VHF or HF antennas, and where a low retracted height is needed e.g. behind a bungalow. It has benefited from a recent upgrade; a 4-pulley tilt system has been introduced to make it easier to tilt. While this is a fairly compact mast it is one of our heavier ones.
