1st problem
The problem
Losing coverage refers to instances where you are mid-transmission with someone and all of a sudden the conversation is cut short, or you find that you can only hear the other person very faintly as if they are whispering. This is down to the problem of poor coverage.
The solution
Poor coverage, we find is commonly a result of incorrect charging procedures and our clients getting a bit sentimental with the batteries and not replacing their two-way radio batteries after the recommended time of 18 months.
By using batteries that aren't charged up correctly or are too old to function anymore, then the power rapidly decreases, which results in poor coverage.
If the issue isn't the batteries and they are brand new and out of the box and have been charged correctly, then it could be that you may need a coverage booster to make sure that the two-way radios can transmit across the entire surface area of your site. These can take the forms of repeaters and leaky feeders.
