A two-way radio is often the only viable alternative to a mobile phone. Not only are they capable of instantly communicating with a large group of people, but a two-way radio also allows you to communicate in places with little or no mobile network coverage.
From campers to construction workers, using a two-way radio is the primary and preferred method of communication.
However, purchasing a two-way radio is more complex than you might initially assume.
There are numerous radios from a range of manufacturers, and these manufacturers offer two-way headsets that differ significantly in price, function, and features.
This brief introduction will help you select the best radio – for business or professional use.
Step 1: Environment – Work or Leisure?
This is perhaps the most important variable when deciding which radio to purchase.
If you need a radio for the work environment, then you’re likely to need a more powerful and professional handset with improved battery life and range, with a larger number of channels so you can communicate with different groups simultaneously.
If you’re using a radio in a harsh work environment, then you should get a waterproof radio or ATEX (Atmosphere-Explosive) certified radio. If you need a radio for leisure purposes (hiking, camping, or sports activities), then you might only need a multi-channel radio with decent range and battery life that isn’t too expensive.
Step 2: Radio Frequencies – VHF or UHF?
Knowing which radio frequency you need is important.
There are two types of radio frequencies that a large number of radios on the market can emit. These frequencies are VHF (Very-high frequency) and UHF (Ultra-high frequency).
A VHF-capable radio can cover greater distances with less power since VHF waves are longer. If you work in aviation, maritime, or outdoor security sectors, a VHF radio would be preferable. If you intend to use your radio for leisure purposes, places like a golf course or an open field are suitable for a VHF radio.
A UHF-capable radio is the popular option, as the shorter wavelengths can penetrate obstacles indoors (thick concrete walls or steel structures).
Glass, however, is an obstacle that a UHF radio might have trouble penetrating.
Step 3: Range – How Does This Affect My Radio?
Most radio manufacturers list their radios’ range under completely obstruction-free conditions. Thus, there is a significant difference between the claimed range and the actual range.
There are a number of factors that could affect a radio’s range.
These include factors such as radio interference from other users, cars, forests, and buildings. Digital radios tend to have the best selection. Of course, you can also buy radios that can transmit both digital and analog frequencies.
Step 4: Power – How Much Do I Need?
The general rule of thumb for radios and power is that each watt of power corresponds to 1 mile of coverage. The higher the wattage, the greater the range.
However, some professional radios with 5 watts of power only achieve a range of 3 miles. This is due to obstacles and weather conditions.
Different radios require different batteries. Most modern radios use Lithium-ion (Li-ion) batteries, which have high capacity and are perfect for daily use.
On the other hand, some radios use Nickel-Metal Hydride (NiMH) batteries, which are impact-resistant due to their high durability.
NiMH batteries also tend to charge faster. However, they are sensitive to heat, as it can reduce their charging capacity over time.
