Tune World Ham Radio Enhancement
|
One of the most critical constituents of a ham radio set up is the antenna. You may have the most highpriced and the most powerful rig on the market today but your signal goes nowhere without a good in the right manner set up antenna system. I will give you a basic introduction to Ham Radio Antennas here. There are numerous dissimilar types of antennas for the ham radio operator. There are directional antennas such as the yagi and quad and nondirectional antennas such as the vertical. Each of these types of antennas have their place. There are wire antennas of all types and sizes depending on the frequency being applied and how much room you have to put one up. Wire antennas for the most portion are semi-directional and normally radiate their signals in a figure eight, broadside to the plane of the wire. Wire antennas may be made directional depending on the design and configuration. So may vertical antennas but it requires more than one antenna and adequate space to erect them. The yagi type of antenna is directional and has various elements that are in general designed for one frequency. There are those that will tune to two or three novice frequency bands but lose numerous power and bandwidth in the design. These antennas are designed to be mounted on a tower or pole type of support with a means of turning them in the direction that you want the signals to go. They are very general with the severe hams because of their capacity to receive and transmit radio signals in the desired direction. The cubical quad antenna, like the yagi, is a directional antenna also. These antennas tend to be very big at a great deal of frequencies. They are very effective directional antennas if you have the room to put them up. Cubical quad antennas are made of wire and galore kind of supporting structure such as bamboo or fiberglass poles. They also are mounted so they may be rotated into the desired direction. Wire antennas are for the most percentage designed with a specific frequency in mind. They may be very simple in design such as a dipole, which is two pieces of wire insulated in the center and installed amongst two supports and comparatively flat or supported by one pole and the sides sloping like an inverted vee shape or supported by a single pole with the wire sloping in the direction that you want the signal to go. These antennas are very simple to design, tune and install and are very general with beginning ham radio operators. Wire antennas may be very complex also with a heap of pieces of wire, signal traps, coils, insulators and tuner components. These antennas are the most employed types of Ham Radio Antennas. Antenna design, tuning and installation may consume a lot of the ham radio operators time, but it is very rewarding when those signals come in and go out where you want them to, with the greatest or most complete or best possible transfer of power. |
