MADE IN THE USA – This Genuine Times Microwave USA Made LMR-240 coaxial cable was developed to provide an extremely low loss alternative with the transmission characteristics of hardline coaxial cables and the flexibility required for WiFi, Ham and CB Radio installations. Times Microwave systems, designs and manufactures high performance coaxial cables, connectors and cable assemblies for a broad range of RF transmission applications. For more than 50 years, Times has been the leader in the development of new cable technologies to meet the demands of evolving RF and microwave applications. This technological, manufacturing and application leadership continues today. Since its inception, Times has been dedicated to the improvement of coaxial cable technology and the development of new and innovative cable products to address the increasingly rigorous demands placed on RF transmission products. The expertise that has provided cable solutions for the demanding requirements of airborne electronic warfare systems has led the way in the development of Ultra low loss coaxial cable for Amateur Radio and Broadband Wireless application as well coaxial cables for shipboard, airborne and ground based military systems. Times has been instrumental in the development of military specifications, including MIL-C-17 for coaxial cables. Unlike other manufacturers with limited product lines, the philosophy of Times Microwave Systems is to select or design the right product for each application. Since we have expertise in both cable and connector design and manufacturing, as well as in assembly of complete transmission lines, we can provide the best technical approach. Our range of manufacturing capabilities is unmatched, allowing us to consider the broadest range of products and choose the best one for the application. If one of our standard products is not the right choice for the application, we have the capability to design a custom product.

CN Tower

CN Tower
The idea of the CN Tower originated from the 1968 Canadian National Railway desire to build a large TV and radio communication platform to serve the Toronto area, as well as demonstrate the strength of Canadian industry and CN in particular. These plans evolved over the next few years, and the project became official in 1972. The tower would have been part of Metro Centre (see CityPlace), a large development south of Front Street on the Railway Lands, a large railway switching yard that was being made redundant by newer yards outside the city. Key project team members were NCK Engineering as structural engineer; John Andrews Architects; Webb, Zerafa, Menkes, Housden Architects; Foundation Building Construction; and Canron (Eastern Structural Division).
At the time, Toronto was a boom town, and the late 1960s and early 1970s had seen the construction of numerous large skyscrapers in the downtown core, most notably First Canadian Place. This made broadcasting into the downtown area very difficult due to reflections off the buildings. The only solution would be to raise the antennas above the buildings, demanding a tower over 300 metres (984 ft) tall. Additionally, at the time, most data communications took place over point-to-point microwave links, whose dish antenna covered the roofs of large buildings. As each new skyscraper was added to the downtown, former line-of-sight links were no longer possible. CN intended to rent "hub" space for microwave links, visible from almost any building in the Toronto area. The CN Tower can be seen from at least as far away as Kennedy Street in Aurora, Ontario, approximately 40 kilometres (25 mi) to the north, and from several points on the south shore of Lake Ontario, 48 kilometres (30 mi) to the south in New York state in the United States.
The original plan for the tower envisioned a tripod consisting of three independent cylindrical "pillars" linked at various heights by structural bridges. Had it been built, this design would have been considerably shorter, with the metal antenna located roughly where the concrete section between the main level and the Sky Pod lies today. As the design effort continued, it evolved into the current design with a single continuous hexagonal core to the Sky Pod, with three support legs blended into the hexagon below the main level, forming a large Y-shape structure at the ground level.
The idea for the main level in its current form evolved around this time, but the Sky Pod was not part of the plans until some time later. One engineer in particular felt that visitors would feel the higher observation deck would be worth paying extra for, and the costs in terms of construction were not prohibitive. It was also some time around this point that it was realized that the tower could become the world’s tallest structure, and plans were changed to incorporate subtle modifications throughout the structure to this end.
On June 26, 1986, the ten-year anniversary of the tower’s opening, high-rise firefighting and rescue advocate Dan Goodwin, in a sponsored publicity event, used his hands and feet to climb the outside of the tower, a feat he performed twice on the same day. Following both ascents, he used multiple rappels to descend to the ground.[7]


Construction on the CN Tower began on February 6, 1973 with massive excavations at the tower base for the foundation. By the time the foundation was complete, 56,000 t (61,729 ST; 55,116 LT) of dirt and shale were removed to a depth of 15 metres (49.2 ft) in the centre, and a base incorporating 7,000 cubic metres (9,156 cu yd) of concrete with 450 tonnes (496 ST; 443 LT) of rebar and 36 tonnes (40 ST; 35 LT) of steel cable had been built to a thickness of 6.7 metres (22.0 ft). This portion of the construction was fairly rapid, with only four months needed between the start and the foundation being ready for construction on top.
To build the main support pillar, a hydraulically-raised slipform was built at the base. This was a fairly impressive engineering feat on its own, consisting of a large metal platform that raised itself on jacks at about 6 metres (19.7 ft) per day as the concrete below set. Concrete was poured continuously by a team of 1,532 people until February 22, 1974, during which it had already become the tallest structure in Canada, surpassing the recently built Inco Superstack, which was built using similar methods. In total, the tower contains 40,500 cubic metres (52,972 cu yd) of concrete, all of which was mixed on-site in order to ensure batch consistency. Through the pour, the vertical accuracy of the tower was maintained by comparing the slip form’s location to massive plumb-bobs hanging from it, observed by small telescopes from the ground. Over the height of the tower, it varies from true vertical accuracy by only 29 millimetres (1.1 in).
In August 1974, construction of the main level commenced. Using 45 hydraulic jacks attached to cables strung fr
