![]() Coax cables have a core conductor wire surrounded by a non-conductive material called dielectric, or simply insulation. Cables RF cables are, for frequencies higher than HF, almost exclusively coaxial cables (or coax for short, derived from the words " of common axis "). ![]() Both types work well for efficiently carrying RF power at 2.4GHz. There are two main categories of transmission lines: cables and waveguides. For these reasons, the RF cable has a very important role in radio systems: it must maintain the integrity of the signals in both directions. From the receiver side, the antenna is responsible for picking up any radio signals in the air and passing them to the receiver with the minimum amount of distortion, so that the radio has its best chance to decode the signal. Its purpose is to carry RF power from one place to another, and to do this as efficiently as possible. The connecting link between the two is the RF transmission line. The transmitter that generates the RF 1 power to drive the antenna is usually located at some distance from the antenna terminals. This project is meant to solve the problem of poor or weak signal reception in the building by creating an uprising receiving antenna for the building which will transmit through a coaxial cable to a transmitting antenna situated in the middle of the building thereby working on the principle of a signal repeater. From the understanding of telecommunication signal propagation, it will be recalled that such high-rise buildings and metal or reinforced concrete creates a divergence to the travelling waves from the nearby transmitting antennas. Engineering departmental blocks) as signal reception have been boosted in the aforementioned place, leaving the complex (especially, the block of offices and laboratories) a blind spot because the building is made up of reinforced concrete with solid metal framework. In the course of the little research and observations carried out, it was observed that signal reception at this point is ironic to its neighboring building (i.e. There is a great need by GSM and Wi-Fi users in and around the Engineering complex in Federal Polytechnic Ilaro for an optimization of signal reception.
