Yet with its interlock- <br />ing triangles it's more resistant to stress and wind - <br />warp. <br />Notice the distance between the feet. This wide stance <br />lessens the load. making the foundation construction <br />less expensive. The wide stance also improves the <br />tower's stability, reducing twist and sway. The unique <br />leg configuration shields transmission lines from <br />falling ice and wind loads. <br />The Landmark tower is designed around an elevator <br />system which is an integral part of the legs. The safety <br />of this two -man lift is bolstered by a mechanical inter- <br />locking safety device. <br />Other advantages of the Landmark tower: <br />• The "window" provides a shielded location for micro- <br />wave antennas to be mounted. <br />• An optional "sky pod" easily accessed by the elevator <br />system, can house the electronic transmission <br />equipment. <br />• The assembly process itself is simple and repetitious. <br />Landmark towers are bolted together for additional <br />strength. There are very few welds and 100% of these <br />are inspected. <br />• The modular design of the Landmark tower makes it <br />easier to construct in locations where limited periods <br />of good working weather exist. <br />• For smaller towers, the Landmark can be designed <br />with trusses which are assembled off -site and carried <br />to their destination by helicopter. <br />• Adelphon's technologically advanced CAD system <br />makes it possible to customize the tower design. <br />Tower designs can be configured to any dimensions, <br />and a record is provided of all loads applied to the <br />structure, including antennas, transmission lines, <br />wind, dead weight and ice loading. <br />Besides the Landmark towers, Adelphon offers a host <br />of other conventional and custom design and build <br />services, including traditional guyed towers.

Thu structure <br />may be equipped to support a top - <br />mounted antenna or any number of <br />side-mounted antennas located at <br />various elevations along the tower. <br />(Shown with optional electronics <br />sky -pod) <br />P <br />.H^ G. ata <br />arilzaM <br />WrnisMa <br />as wp.: wa <br />lownxis" Oral <br />Ian ix- II <br />us 9 <br />LANDMARK TOWER, TYPE 2: <br />This tower has a graceful curve <br />which sweeps upward from a wide <br />base stance to a narrower conhgura- <br />don and then widens to a slightly <br />wider dimension at the top. This <br />structure may be used for mounting <br />antennas which must be separated <br />by a larger disunce. Additionally, n <br />is more rigid than a Type 1 structure <br />and provides more windows for <br />mounting microwave antennas along <br />the height of the structure. Micro- <br />wave antennas may also be placed <br />inside the windows and the windows <br />covered with a screening material, <br />making them invisible from ground <br />elevation.
