Do stubby antennas work as well as the regular length 2 way radio antennas?

When we want the walkie-talkie to get a longer and wider range. We will have meatoder ways to improve this. But the simplest and most effective improvement that will have the greatest impact is to replace the antenna. It is important to note that FRS radios do not allow external antennas. Usually FRS radios come with a fixed antenna. So to replace the antenna you will need to choose a better walkie-talkie. If your walkie-talkie supports antenna replacement, then this article will be helpful for you.

Does a short antenna have the same effect as a regular antenna

Although replacing the antenna may sound like a simple operation. But there can be a lot of problems with it.

The first thing that needs to be made clear is that the higher the frequency and the shorter the wavelength, the shorter the antenna. Although the length of the antenna is usually taken into account when choosing an antenna, the final choice is based on the frequency written by the walkie-talkie. Usually the physical length of the walkie-talkie longer antenna gain is relatively higher than the same technology short antenna, handheld walkie-talkie antenna in addition to consider their own gain often also have to consider the overall portability and appearance coordination, for some dual-band multi-band walkie-talkie antenna design to additional consideration of the various frequency bands, so it is often only sacrificed some of the gain.

In electromagnetism, antenna gain is a key performance parameter, which combines the antenna's directionality and radiation efficiency. In a transmitting antenna, gain describes how well the antenna converts the input power into radio waves propagating in a specified direction. In a receiving antenna, gain describes the effect of the antenna in converting radio waves arriving from a specified direction into electrical energy.

This measurement is in decibels and is measured in dBi or dBd. 

For amateur radio enthusiasts to maximize the potential of their walkie-talkies, there are antennae that can be used. For example, if ultra-portability is a priority, you can choose a short stick antenna, which improves the overall portability of the walkie-talkie, even though the gain is not very good.

However, the antenna of the walkie-talkie is not divided by length, it is divided by the frequency of the walkie-talkie. The antenna must be matched with the frequency of the walkie-talkie in order to communicate well, the long antenna is not necessarily a good signal, the short antenna is not necessarily a poor signal, the signal is good or bad mainly with the frequency of the walkie-talkie and the band is related to the walkie-talkie antenna just play a role in laying.

If the frequency is the same, the long signal is strong, because the short antenna must have used the loading technology, the efficiency will be reduced; if the frequency is different, it can not be compared!
