Standard Mast 12m

The Standard Mast 12m is a substantial free standing mast built to exacting standards and is the preferred antenna support system of our range. It was the first type of mast we made and is the mast from which all our other masts are derived.
  • Capable of supporting a wide range of antennae
  • Can be simultaneously used for UHF, VHF and HF antennas of medium size
  • The 12m version benefits from both greater height and a heavier ground post, plus the larger optional winch in order to accommodate the extra cable length
