Point-To-Point Microwave Link Between Globe Tower in Cotabato-Davao Road, Kidapawan City and Malasila, Makilala, Cotabato

The document summarizes a proposed point-to-point microwave link between Globe Tower in Cotabato-Davao Road, Kidapawan City and a repeater site in Malasila, Makilala, Cotabato. It discusses selecting the sites based on line-of-sight and proximity to power lines. Equipment to be used includes a self-supporting tower, parabolic dish antenna, waveguide transmission line, and active repeater equipment. The total estimated cost is 996,876.48 Philippine pesos.

Point-to-point Microwave Link between Globe Tower in Cotabato-Davao Road,

Kidapawan City and Malasila, Makilala, Cotabato

SITE SELECTION

In the site selection, Google Earth Pro was used to check for line-of-sight in choosing potential
sight locations. The microwave link communication design, the Globe Tower is in Cotabato-
Davao Road (7° 2'19.69"N, 125° 1'30.81"E). The repeater is in Malasila, Makilala, Cotabato
where the proposed tower will be built. It is 0.37 kilometers away from the Cotabato-Davao
Road (Malasila National Highway) which means it is near power lines (6°56'24.44"N, 125°
8'0.94"E). The transmitter and receiver sites is verifying that there is no natural and man-made
obstructions between them.
Globe Tower (Transmitter)

The Globe Tower is located in the intersection of Kidapawan-Allah Jct Rd and Paco-Arakan
Highway along the Davao-Cotabato Road.
Repeater Site

(Malasila, Makilala, Cotabato)


The repeater site was chosen due to the fact that (1) it is an empty lot; (2) it is far from
residences; and (3) strong signal coverage is needed in the area.

Transmitter to Repeater Site: 16.3km aerial distance

REPEATER TOWER

The tower repeater is selected due to the following considerations:

1. Rigidity
2. Height
3. Wind Loading
4. Land Area
5. Cost
Since the area (Malasila, Makilala, Cotabato) does not have any high-rising building, a self-
supporting tower was selected for this proposal since it can be built on grounds. The advantages
of self-supporting tower is that it is the strongest among the towers and has the greatest
resistance to ice and wind loads.

ANTENNA

The antenna on the repeater will be a parabolic dish antenna at 20m above ground level. This is
chosen due to its high directivity. Parabolic antenna application usually includes point-to-point
communication. In this design, parabolic dish with parabolic reflector will be used to provide
high power gain which is important on a point-to-point microwave communication system.

TRANSMISSION LINE

The transmission line on this proposal will be an elliptical waveguide because the transmission
losses are less than that of coaxial cables.
