An Introduction To End Fed Long Wire Antenna

By Cynthia Schmidt


The length of antennas does not really matter on its wavelength of the radio waves that has been used and those are helpful no matter where that is placed. This brings convenience and that reason made individuals to want it. Antennas are considered to be great alternatives especially with dipoles which some people said to be very efficient. The bottom line is that everything is beneficial.

However, we must be aware that this kind of system that we shall tackle about can cause more interference problems because this can get really noisy along the way. The best part is that these are cheaper and even easier compared to the other devices out there. In fact, this can receive a reliable connection in terms of power supply. To know further about this unit, here is an introduction to end fed long wire antenna.

What is in this product includes one earth stake which was made of copper and that has been connected to ATU or radio that contains a thick earth cabling. A tip is to keep that shorter if possible. Four and more wire radials may be added as long as that is at least a quarter waves long to the operations in the lowest frequency. That shall run to a range of directions and might be buried as well.

Dealing with the proper length is nothing to confuse about even though others struggle on that. The traditional way utilizes about the quarter as we mentioned before. Matching impedance to radio can be easily done even if that is not its standard way because its problem gives that to lower.

Electromagnetic radiation might take place and that causes the interference like hot microphones for example. Matching antennas to other bands is never easy too since that already has high impedance on its feed point. In other words, we better choose an average length on the impedance which means it should not be too high or low.

An extremely reliable unit lies a W3EDP which contains wire fed that reaches to eighty five feet that is pressed against counterpoise on seventeen feet. Some people agree and disagree of a counterpoise size if that should be about ten meters and twenty perhaps. We need only to focus in acquiring ATU since that has been really significant.

Our gardens could even be placed with the product as long as we depend on its layout. Wires reaching the window, house, and property are concrete samples of these. No disturbances could happen anyway if everything is set in a design with strategy.

Feeding an antenna with coax might be needed. That causes the radiating element to go away which lessens the chances of having EMC problems. Using coax can give us many losses but if the coax is not really long, then that shall not be bad at all.

W3EDP performs well on eighty and forty meters which is not that different in having a twenty. Take note to have a good earth so that RF disturbances in its shack can be not much of a problem. Clearly, that sums up how this product can both be an advantage and disadvantage yet it depends on us how to balance its factors.
