When making antenna out of wire, does curling it affect the outcome? - rf antennas 5 stars all the way!!!best electronics gadget ever!!
If wire antenna loops affect the outcome?
I have a wire antenna. This is a 433 MHz antenna for RF use. The cable consists of components of a CAT-5 (Ethernet) cable. Instead of the cable directly, I can just shut up?

Curling has an effect. Instead it involves changing the inductance. The effect of this is to change the resonance point of the antenna. In other words, which would have to swing at the same frequency, the antenna should be shortened.
It also has implications for the opening of the antenna. Do not cut a shorter antenna, "" the same amount of land and therefore the induced voltage is lower. In other words, a short antenna is as good as the antenna length.
Assuming that you are trying to collect only the signal of 433 MHz could do better with a straight 69.24cm (quarter wavelength) wire at right angles) to the direction of the signal (usually upward like a car antenna.
Remember, a coil when the direction and distance to get the signal is known. Please correct the spiral antenna can not pick up anything. If you do not object, the direction for the occasion, this may be a problem.
And if you have a CAT5 cable, make sure to remove the protection or the insurance company will not receive a signal.
Wrap the cable as described, can certainly influence how the functions of the antenna. After the many things that the sheathing of the cable could make a better antenna, or can one of the worst of the antenna. Variables The topic is too technical and too numerous to elaborate on why this is so.
Yes, there is no difference
