    ❓ Why is the antenna of a radio located outside the device? I finally understand! The walkie-talkie has been around for almost a century, which is half a century longer than cell phones. While cell phones have evolved from the bulky "bricks" of the past to today's sleek smartphones, walkie-talkies still retain that “classic” look with external antennas. So, is the external antenna a result of technical limitations, or is there more to it? First off, walkie-talkies are a type of radio communication equipment that relies on radio signal “working frequencies.” In China, cell phones typically operate between 900MHz and 1800MHz, while public walkie-talkies (civilian models) are regulated to operate between 409 and 410MHz. To transmit radio signals efficiently, the antenna must be designed to be half the wavelength of the frequency it’s operating on. The formula for wavelength is the speed of light divided by the frequency, meaning higher frequencies have shorter wavelengths. As a result, cell phones have much smaller wavelengths compared to walkie-talkies. When designing an antenna, it’s usually not practical to make it exactly as long as the wavelength, but ideally, the longer the antenna, the better the signal quality. Additionally, since walkie-talkies are often used in scenarios where appearance isn’t a primary concern, the design of the antenna takes precedence over aesthetic considerations. Given that walkie-talkies operate at relatively low frequencies compared to cell phones, they require longer and larger antennas to ensure effective signal transmission. This is a key reason why walkie-talkies feature external antennas. #radio #antenna #Change #technology #RETEVIS

    Ideal Applications for the Ailunce HA1G Hiking and #camping: The IP67-HA1G's #waterproof and durable design makes it ideal for hiking and camping in unpredictable weather conditions. Even in dense forests or mountainous areas, its long range ensures that you can stay in touch with your team. OFF-ROAD: Even in remote areas, the HA1G's repeater feature enables #longdistance communication. Its rugged design means it can handle the bumps and knocks of the backcountry with ease. HUNTING: #Hunters can rely on the HA1G's powerful transmission capabilities to communicate with their team, even in areas where cell phone reception is not available. The radio's waterproof capability is also a plus for early morning hunts in wet conditions. EMERGENCY PREPAREDNESS: In the event of an emergency, the HA1G's ability to tap into a GMRS repeater to communicate with rescue teams or other emergency services over longer distances can be life-saving. FARM: The 5W #GMRS radio is powerful enough to easily connect to a GMRS repeater. They choose IP67 waterproof and dustproof radios because farm work is subject to rain and a lot of dust is generated when the harvester or tractor starts working. 🧷 https://lnkd.in/gb7CNyAb

    The 2025 SWL Contest is just two months away! The goal is to have the most shortwave (SW) transmitters tuned in on the SW band and the highest number of stations listening on the medium wave (MW) band. Our friend Franck Fzeroduw is organizing this event, and we really hope you’ll join in! 🤩 Prizes are sponsored by RETEVIS, so don’t miss out! For all the details, check this out: https://lnkd.in/gxj7fUfY
