Standard Mast 12m

Gallery

This mast is free standing and was the first type of mast we made, it is the mast from which all our other masts are derived. It is a substantial mast built to exacting standards. Like all our other masts, it is built from the most suitable materials and has evolved into the preferred antenna support system of our range.
It is capable of supporting a wide range of antennas and can be simultaneously used for UHF, VHF and HF antennas of medium size.
The 12m version of this mast benefits from both greater height and a heavier ground post. It benefits from the larger optional winch in order to accommodate the extra cable length
