Telecommunication Monopole Antenna Tower

Telecom Tower Monopole

: Monopole Tower is a kind of tower that consists of one stem or one pole anchored to the ground. According to its cross-section, Monopole Tower is divided in to two types

.Cilcular-pole is a kind of monopole having a cross section/panel diameter similar from bottom to top

.Tapered-pole is a kind of monopole having a varied cross-section diameter size that when the used diameter is more up will be smaller

Pipe Monopole Tower – Monopole Tower Manufacturers

.Kehang monopoles are single member self-supporting structures used in urban areas where space is limited
.We offer steel tapered, slip-sleeve monopoles or flanged pipe poles depending on your communication application

 

SLIP-SLEEVE

Designed to carry wireless and microwave communication equipment, our steel tapered monopoles are made of high-strength steel with minimum yield strength of 65 ksi. They are constructed of slip-sleeve tapered sections. Each order includes steel templates to assure proper base bolt alignment. Our monopoles have step bolt working rings at handhole levels and loop step bolts at all working points. They are available 12, 16, or 18-sided and in heights that meet your specifications. A factory-applied finish coat is available upon request

FLANGED PIPE POLES

In addition to providing slip-sleeve monopoles, Kehang offers pipe poles that are internally and externally flanged. Each order includes steel templates to assure proper base bolt alignment. Designed with safety in mind, we provide step bolt working rings at handhole levels and loop step bolts at all working points. Our flanged pipe poles are capable of carrying a variety of communication applications and custom-engineered to meet your height specifications

Light Standard Pole

The Light Standard Pole is a relatively small diameter CSA–S37 compliant pole that can be used to replace or augment light standards. Its height ranges from 14.9m to 18.6m (49 to 61 feet) and it is ideal for microcell densification projects

Micropole

The Micropole is a relatively small diameter, short CSA–S37 compliant pole that can be used where loading can accommodate outside mounted antennas. It ranges in height from 14.9m to 34.4m (49 to 113 feet) and is ideal for urban areas and medium–density sites.

.Kehang’s innovative micropole is helping our clients expand their urban networks

Mono–pine

Kehang’s Mono–pine is an innovative solution for wooded settings. It is a step–tapered pole ranging in height from 24.4m to 36.6m (80 to 120 feet), with artificial branches and needles covering the upper part of the pole. The Mono–pine is designed to blend into a forest and is virtually indistinguishable from the surrounding trees.

.Kehang’s innovative Mono–pine has made headlines in Ontario’s cottage communities

Rapid–Deploy Monopole

The Rapid–deploy Monopole is a temporary or permanent tower solution ranging in height from 10m to 18m (32 to 60 feet). It is a CSA–S37 compliant pole that can be installed in less than two days with a ballast design that eliminates any foundation requirements. It is ideal for microcell densification projects in urban settings for seasonal requirements.

Flag Pole

The Flag Pole has a circular face and constant diameter, which enables antennas to be mounted inside the pole, under the shrouding material. It ranges in height from 22m to 40.2m (72 to 132 feet) and is ideal for medium to high–density sites, where an unobtrusive appearance is required.

Standard Monopole

The Standard Monopole is a step–tapered pole ranging in height from 24.4m to 48.8m (80 to 160 feet). It has a small footprint, making it ideal for heavy–density or smaller sites and accommodates multiple panel and dish antenna installations

TYPE OF MONOPOLE

Monopoles shall be self-supporting and galvanised tubular steel type with body extensions. The body extensions shall be applied on the slope so that legs are suited to the original slope of tower-site so that excessive land cutting around foundations and land collapse is prevented
.The following monopole types shall be designed for the project in order to meet various monopole positions and loadings economically

Monopole Tower

This Tower are of a single pole design and are general used in cellular and personal communication service
In comparison with other form masts, a monopole tower has both advantages of light weight and small space requirement. It free standing and usually built cylindrically or with multiples sides. Monopole towers are supplied completely with shafts, platforms, ladders, rest platforms and anchor bolts as required. There is a lower hole in the surface of bottom body, upper hole at the platform place. Antenna bracket fixed in the enclosure of platform. The ladder is inside of the tower body. So the design sometimes makes it a decorative building in some places. yhis tower is regularly used in power grid construction and communication systems. Especially in some zone confine land .It can be used on either city or suburb areas

The advange of monopole tower

Reduce the weight by 10%–20% –
 Reduce the wind press of the tower –
