When it comes to Walkie Talkies, many people get embarrassed about the needs of manufacturers. It would probably help somebody clean up the air in this way to help those who try to distinguish the ridiculously high demands of many Walkie talkies. Keep in mind that challenging radio environments quickly reduce the range to at least 300 meters or about a mile in somewhat better conditions. Buildings block or signal the signs as a mirror. Steel grades are even worse, and colored windows are just a little better. Only a lot of height will get the maximum values that the manufacturer requires. In any case, manufacturers are trying to exploit their radiation in unrealistically unusual ways, using the Florida Accessible Accessibility Plans, with raised test platforms.
Talk about bi-directional radio frequency:
First, always buy a radio that says GMRS or General Mobile Radio Service. This service is permitted up to the maximum permitted by the government; about 4 watts. FRS or Family Radio Service radios are automatically limited to 1/2 watt; it was hardly enough to be in the street. So keep the FRS away unless you want to buy games and you do not need them for real communication and security. Most of the better radios are combined as GMRS / FRS, but the walkie talkie is automatically reduced to 1/2 watt on GMRS channels.
Walkie Talkies is not a cell phone
GMRS radio (with a GMRS channel) can do a lot with 4 watts of energy. This is a lot of power, considering that most digital mobile phones these days work about 500 milliwatts or less, most of the time. However, cell phones use near-invisible networks around "cellular" locations around the corners, hills, and mountain tops of high buildings, so they rarely need a few hundred yards. Cellular sites use altitude and energy to increase the range of the small cell phone signal. The walkie talkie has to do things hard without giving a cellular space. However, four watts quickly drain the battery and require somewhat more expensive, larger and heavier internal components to handle extra energy.
To put it this way, anyone who has spent time in the field with these things knows that reliable communication is key. Certain settings, such as radios in car, city streets or heavily forested areas, will also reduce the range of the most powerful radios from miles to a few hundred meters. "Line-of-site" is the rule of this type of radios, so if you have a height, the range is greatly increased. With obstructions the signs can be absorbed or reflected.
The rule of the inch, even if one just has fun with these radios, the stronger the better. That's why I always recommend spending extra $ 20 and things that use the lowest amounts. These are found on radios that are in a range of "25 miles" or greater and each outputs 4 watts on GMRS channels. These extra watts help to work with metallic finishing windows, wooden frame and concrete structures. Trees and rocks in the wilderness are the same obstacles to radio signals, but as an outdoor security device the radios have to work reliably so the maximum performance allows for more states of mind to track children and hikers. You can always dial the battery to protect the battery spindle when you need it.
So, unless you really need the small 5.5-inch Cobra LI5600 radio, you might want to use the Cobra seven inches (including the antenna) LI7020 or LI7200.
Radios are inexpensive for the whole family. However, when in the province, keep your expectations realistic. Read the instruction manual, keep the simplest possible settings, and go both in the real and urban jungle!
