The radiation pattern of a T-antenna is that of a simple vertical of the same height, i. 1- 1 1/2″ PVC Pipe. This antenna is unique in that it is enclosed entirely in 3/4" PVC which makes the design a little more complicated. SCaN's Deep Space Network currently has two different types of antennas: High Efficiency (HEF) and Beam Waveguide (BWG). The dimension of the antenna cannot be easily changed, however the radiating element is a small piece of copper which can be easily cut and bent. Learn this aspect of electronics online because a good understanding of what happens after a signal leaves a transmitter and before it enters the recever itself is essential for anyone involved in radio or wireless technology. Helically Loaded Magnetic Loop Antenna. 4 GHz with gain 11 dB for outdoor place. Optimized antennas will have dimensions of the same order as the wavelength of operation.

Though having a narrower bandwidth than log periodic air band antennas, yagis are easier to construct and provide high gain near the design frequency. If the antenna is placed low, close to the ground, and the counterpoise is extended to one side, your antenna will display a fairly directional pattern – you can experiment to find what works best for you. I was lucky and didn’t need to make any further adjustment for lowering the SWR. The antenna was a bit long so I slowly shortened it, about an inch at a time. The pattern of left is for a two-element 20-meter quad 35 feet high (1/2 wave high). Kent accepted this as a challenge to design a really good antenna that could be built with little more than ground wire, coax and a wooden boom. The gain of a highly directional parabolic antenna serves to amplify a weak signal; this is one reason why this type of antenna is frequently used for long distance links. One area that is still open to amateurs is in antenna building. The gain of an omnidirectional antenna can be increased by narrowing the beamwidth in the vertical or elevation plane.
