When Buying a Walkie Talkie, is it Better to Choose a Long Antenna or a Short One?

We all know that the antenna of the walkie talkie is proportional to the transmission and reception of the walkie talkie. The antenna is a device that transmits electromagnetic waves into the air. We usually use walkie talkie, in order to send more energy (or power) to the air, so that when the other party receives the signal, there is enough energy to restore the content of the information. The antenna is an important part of the transmitting part. Today, Xiaobian will talk with you about the choice of long antenna or short antenna when buying walkie talkie?

In fact, the antenna of the walkie talkie is not distinguished by the length of the antenna, but by the frequency band. Although the antenna is usually selected with long or short antennas, the final selection is based on the frequency written by the walkie talkie. You can look at the bottom of the antenna. Generally, there will be remarks at the bottom of the antenna to explain the applicable frequency range of the antenna. If the frequency written by the walkie talkie is within this range, the antenna is applicable. Of course, each interphone manufacturer produces each interphone with a central frequency.

2 Practical Reasons to Use Two-Way Radios

1. Safety

Safety is the No. 1 concern for any professional cleaner or custodial firm. According to the U.S. Bureau of Labor Statistics, in 2015 custodians and cleaners suffered an average of 50,000 injuries that required them to take days off from work. Even more staggering, the industry is in the top 20 most hazardous occupations, along with logging, professional fishing, and roofing.

Cleaning injuries can range from accidental exposure to hazardous chemicals to slips, trips, and falls. Two-way radios are valuable tools for anyone who works in an isolated or remote area as custodians often do. Unlike cell phones, which may not be able to receive or send a signal and can be hard to operate in the midst of an emergency, two-way radios can provide immediate and reliable communication.

For example, most professional-grade, two-way radios have a programmable emergency alert button located on the top of the unit. During an emergency, workers can push the button to immediately send out an alert to either the entire network or a specific user. The signal will reveal which radio sent the alert. This feature allows two-way radio users to instantly communicate with each other while maintaining distance between them, which is especially valuable in this age of the highly contagious coronavirus.

2. Efficiency
A two-way radio is a useful tool for maximizing efficiency in any facility setting. Consider a cleaning crew dispatched to a large office building with multiple floors. One worker may encounter a problem on the seventh floor that requires a second opinion or supervisory instruction. With a professional-grade, two-way radio, the worker can instantly notify another team member or supervisor to receive the additional support needed to get the job done. Not having to leave a location to secure help saves the worker time and saves the company money.
