What is the gain of a rubber duck antenna?

2.2
This single band rubber duck portable antenna has a frequency range of 2.4 GHz to 2.5 GHz and a 2.2 nominal dBi gain.

What is a disadvantage of the rubber duck antenna?

The disadvantage of the “rubber duck” antenna supplied with most handheld radio transceivers is it does not transmit or receive as effectively as a full-sized antenna. A good reason not to use a “rubber duck” antenna inside your car is the signals are significantly weaker than when it is outside of the vehicle.

Are rubber duck antennas good?

Effective aperture. Like other electrically short antennas the rubber ducky has poorer performance (less gain) due to losses and thus considerably less gain than a quarter-wave whip. However it has somewhat better performance than an equal length base loaded antenna.

How do you make a rat tail for a radio?

For a 2m rat tail, simply cut a 19.5-in. piece of hookup wire, strip one of the ends, then form a loop that will go over the antenna connector where the rubber duck screws in. You can solder the spot where the end of the wire forms the loop so that the loop stays intact.

Is a rubber ducky antenna a dipole?

Note that rubber ducky antennas for lower frequencies (ie, CB, two-way radios, etc) are typically not a half-wave dipole, as the lower frequencies mean a longer wavelength.

What is the gain of an antenna Hamstudy?

Antenna gain is a measure of how omni-directional an antenna transmits it’s signal. An antenna with a gain of zero would perfectly radiate in all directions, so depending on your purposes, gain could be better as a large number, or better as a small number.

What is a 5dBi antenna?

This antenna would typically replace standard 2dBi antennas, which are normally shipped with this class of wireless device, in order to increase the range and/or expand the coverage area. With this 5dBi antenna, theoretically a distance of about 500 meters can be covered. Specifications: • Gain: 5dBi.
