The PA2 series of masts is a commercially available solution from South Midlands Communications in the UK. The masts come in a variety of configurations based on 2" diameter 6' long aluminum sections. The mast is assembled flat on the ground and then pulled up into position as shown in the sequence of pictures below.
We currently have several unused kits in stock of the PA2/B48 configuration that include a 48 foot center pole and two 12 foot poles to carry the ends of an inverted-V antenna. The kits include all of the required hardware, rope guys and anchors to install the mast. Includes a halyard with pulley for pulling up wire antennas to the top of the mast. The main mast will handle about 3 square feet of antenna. For additional details refer to the complete specifications and installation instructions (note that these instructions are for a slightly different configuration than we are offering). The kit is packed in a cloth bag and weighs approximately 110 lbs. Sold Out.
