The very top of the tower was designed as a 335-foot (102m) TV and radio antenna that would be built on the ground and lifted by sections onto the top of the tower. Originally its 36 pieces were to be put into place by a crane, but when a 10-ton Sikorsky S-64 Skycrane helicopter became available it was used to lift the pieces instead.
Features • Precision swaged legs for perfect fit • “Everdur” welded for high strength • Sleeve bearing for masts up to 1.66” (4.2 cm) diameter • Each section subjected to pressure testing to ensure all weld points pass the minimum strength requirements The result is a safe and reliable tower - look for dimple on braces.
Now that the new tower is built we are removing the old tower. The old tower's guy lines will be used on a new Rohn 55G 320-foot tall tower. Two curtain antennas, one for 80 and 40 and the other for twenty through ten meters will be installed. I'm reasonably sure we have the highest gain antennas on Europe of anyone in the USA.
Cell Phone Towers and Radiofrequency (RF) Radiation Safety Cell Phone Towers Cell phone towers are also known as base stations. The base station antennas are usually located outdoors on rooftops, sides of buildings, or inside church steeples. The antennas are also situated on towers or monopole structures.
• Place the antenna base against the concrete where you want to mount the antenna. Make sure it’s level. • Mark the surface through the holes in the base where you’re going to mount the antenna. • Set the base aside and drill a 0.1575” pilot hole at each marked location. Remove any excess dust from the holes.
Tower construction crews moved in on February 6, 1973, and started to remove over 56 metric tonnes of earth and shale for the foundation. Once the foundation was ready, work began on the CN Tower’s 335 m (1,100ft.) concrete shaft, a hexagonal core with three curved support arms. This involved pouring concrete into a massive mold or ...
