What if I need to talk over a greater range?
How much greater range do you really need? It may be possible to use a telescoping antenna on a VHF handheld 2 way radio, greatly increasing your usable range versus that provided with the short flexible antenna typical of most handhelds. You may also have the option of installing an outside antenna at one end of the link. Depending on your desired coverage area, you might see a 2 to 5 mile range – or more if one end is high above the other and clear of obstacles. If you still need longer range, you should consider using a “repeater”. A repeater is a specially built receiver and transmitter pair that receives signals from low power handheld or mobile 2 way radios and retransmits them using a better antenna and more transmitter power. Consequently, the repeater can extend the range of a typical handheld by great distances. The actual distance depends on the system design and location. Where a repeater is located high atop a mountain, it may be possible to communicate to another station 100 miles away. For commercial users, you can rent use of an existing, shared repeater system. You can also inquire about using Specialized Mobile Radio Service (or SMR) systems that operate similar to the basic repeater and provide coverage over wide areas. Look under “Radio, 2-way” in your telephone directory.

Is it worth the risk to buy cheap 2 way radios?
Beyond the risk of fire is the risk of not getting a good quality product and the risk of losing your product warranty. When you buy cheap 2 way radio, you will face a lot of challenges. Inexpensive 2 way radio is often unable to perform as advertised, and may not meet your needs.
Inflated Range
The first major flaw with a discount 2 way radio is that the operating range is often inflated. Some manufacturers list the range as a product of standing in a vacuum, with a straight line of sight and no interference between the two radios; a scenario that is never likely to occur naturally. In reality, many cheap 2 way radios have anywhere from one half to one quarter of their advertised range, meaning that a one- to two-mile 2 way radio may have a functional range of half a mile or less.
Never use an inexpensive 2 way radio across large distances unless you’ve spoken to plenty of people who have used it and tested the range in a variety of scenarios, or read reviews from many users validating the range.
Low Battery Life
Another major disadvantage of inexpensive 2 way radios is potentially low battery life. In some cases, if you’re using standard batteries that you can purchase at any store, a cheap 2 way radio chews through them in a matter of hours.
If your radio uses rechargeable 2 way radio batteries, you’ve got a bigger problem, since you can’t simply replace the batteries with the disposables sold in most stores. You’ll need to carry spare batteries and be prepared to charge them regularly.
The two way radio can be a life saver in many dangerous situations. But the situation may become worse when you get cheap two way radios that have potential quality defects such as inflated range, poor speakers or low battery life. Do you think it worth the risk?

Police Multi-module 2 way radios pass expert evaluation
Recently, the Ministry of Public Security Period Summary Symposium for the Team Trial of Police Multi-module 2 way radio was successfully held in Hangzhou.
In 2007, in order to improve police equipment, optimize investment, implement equipment standards, and comply with the Golden Shield Project, the Equipment and Finance Department of the Ministry of Public Security gave its official approval to the project application for new communications equipment R&D.
From October 2008 to May 2009, the Ministry of Public Security trialed the 350M Police Multi-module 2 way Radio in the public security systems of six cities, including Daqing in Heilongjiang, Hangzhou in Zhejiang,Kaifeng in Henan.
It is recommended that the R&D organizations heed the suggestions and advice of the trial organizations to further improve the 350M police-use multi-module2 way radio, and accelerate the finalization of its design so as to put it into production as soon as possible.

2 way radios for golf courses
With golf courses, staff can be spread out over a fairly large area, making communications costly and time consuming. 2 way radio allows staff to communicate instantly, saving money by increasing efficiency and allowing you to provide better service to players. 2 way radios can provide benefits for many different segments of golf course staff, including: grounds keepers, irrigation specialists, course managers, caddies, teachers, pro shop staff, restaurant managers, beverage cart operators, maintenance staff, custodians, and more.
Golf courses rely on 2 way radios to keep their managers, groundskeepers, and maintenance personnel connected. They’re able to take care of safety issues before they happen. And they can get both the players and personnel inside before inclement weather forces them into dangerous situations.
With golf courses, exactly which radio to choose is not as straightforward as with some other types of businesses. Radios using UHF frequencies are the most popular, as they work well both indoors and out. However, radios using VHF frequencies will provide better range if you are using the radios in a fairly open area and only outdoors. Very large golf courses will require powerful 4 watt radios or even repeaters in order to get communications throughout the entire area, while standard two watt radios are sufficient for most.
Here are some helpful questions to ask when looking for the right radios. 2 way radios are an essential part of any golf course. Before purchasing radios, there are a few questions you should ask in order to determine the best radio for the golf course needs.
Are your radios exposed to environmental elements like humidity, rain, heat, sand or dirt?
If so, you will need a radio that can handle environmental exposure.
Are your radios used every day or for long periods of time?
It’s important to invest in quality products to save you money over the life of your radio.
What is the size and topography of your golf course?
The selection of 2 way radios for your course will depend on the coverage area you need. Be sure to consider future growth or expansion of the course.
Are employees encouraged to solve problems through instant communication?
Radios can provide extra security for both staff and guests. In addition, they are a useful tool for providing guests with immediate help at an event, hotel room, and restaurant or by the pool.
Keeping Golfers golfing is most important to a successful golf course. Use 2 way radios to keep Rangers, Starters, and Cart Staff communicating to keep the time timely, the flow of play smooth, and the Golfers happy.
