What is a rubber duck antenna used for?
The rubber ducky antenna is a form of normal-mode helical antenna. Electrically short antennas like the rubber ducky are used in portable handheld radio equipment at VHF and UHF frequencies in place of a quarter-wavelength whip antenna, which is inconveniently long and cumbersome at these frequencies.
How does a rubber duck work?
Well, it used to be, but now, this seemingly innocuous label has been applied to a potentially nefarious hacking tool. The rubber ducky looks like any other USB flash drive, but when you insert the rubber ducky, the computer perceives a keyboard, and it allows that “keyboard” to enter a host of preset keystrokes.
There are different shapes, sizes, materials for the rubber duck antennas. Therefore, before choosing one that works best for you, it is important you consider the types. These include:
Flexible antennas
Fixed-position antennas
Wire-clamp antennas
Are rubber antennas good?
Rubber duck antennas deliver decent gain. However, it offers less gain compared to the regular whip antennas.
Can we refer to the rubber duck antennas as a dipole?
You cannot because the rubber duck antenna is not a dipole. Rather, they are short monopole antennas.
What is the nominal gain of rubber duck antennas?
Rubber duck antennas have a nominal gain value of 2.2dB.
