Several points that should be paid attention to when buying marine VHF radio

Marine VHF radio is one of the necessary communication equipment for ships. Because its cost performance and effect are much better than mobile phones, Marine VHF radio has become the most widely used communication equipment in ship communication. There are many brands of VHF marine radio. How should we choose and buy them?

VHF marine radio can be divided into two types according to their appearance, hand platform and ship platform, but their frequencies are unified and fixed and can not be adjusted. Of course, some VHF marine radio have the function of expanding channels and can expand the frequencies of other V segments.

The most commonly used VHF marine radio are retevis, echo screen, cobra, standard horizion and so on. Their power is 1-5w. When using high power, the communication distance can be increased. The frequency is 156-164mhz, plus 10 weather channels and emergency alarm channels to form the channel composition of VHF marine radio. There is one more emergency alarm button on the slipway than on the hand platform. Since the frequency standard of VHF marine radio is unified, no matter which country's sea area, as long as the VHF marine radio is used, it can communicate.

Due to the particularity of VHF marine radio, we put forward some special requirements for our purchase of VHF marine radio, focusing on power supply, operability, waterproof and call distance.

1. Power supply

The common marine interphone power supplies include lithium battery and nickel hydrogen battery. Generally, there is no long-term charging power supply at sea, so the standby and talk time of the walkie talkie is a more important parameter, otherwise it will be unable to communicate due to insufficient power during use. Generally speaking, the VHF marine radio with lithium battery has a long service time and needs to be equipped with backup battery.

2. Operability

The most direct requirement in the use of VHF marine radio is simplicity. The simpler the better. Some VHF marine radio integrate functions into the menu. Although the interface looks neat, it brings great changes to the operation. Generally, the key requirement for VHF marine radio is to be able to operate with one key. One function can be met through one key to realize convenient operation when using.

3. Waterproof

The marine environment is generally humid, and the waterproof performance of VHF marine radio is required to be high. Only with high waterproof performance can it be used at sea for a long time, otherwise it is easy to get water and cause the failure of VHF marine radio. Of course, the waterproof performance of good VHF marine radio is qualified, but the price is not cheap. Those with money can consider buying them.

4. Call distance

The communication distance of VHF marine radio is between 5-20 nautical miles, the handset is generally between 5-10 nautical miles, and the slipway is between 10-20 nautical miles. If the purchased VHF marine radio can not reach this distance in good weather, it indicates that there is a certain problem with its antenna or power. A VHF marine radio that can not meet the long talk distance can not be regarded as a good VHF marine radio.
