Quick Answer
A family with two to four members typically requires two GMRS radios. However, it's recommended to have at least one extra radio for guests or temporary visitors. This will ensure everyone can stay in touch during emergencies or group activities.
Setting Up a Family Network
To establish a reliable family network, consider the following factors: number of users, terrain, and expected use cases. A two-member family can get by with one base station and one handheld radio, while a larger family may require additional base stations and more handheld units. When choosing radios, look for ones with sufficient channel capacity and range for your needs.
Radio Selection and Channel Allocation
Typically, a family of four will need at least three dedicated channels for communication. Each channel can accommodate one to two radios, depending on the device’s capabilities. Handheld radios usually have less capacity than base stations, so plan accordingly. Consider the following channel allocation: one channel for the base station, one for the main handheld radio user, and one for guests or temporary family members.
Additional Considerations: Repeater Use and Network Extension
If you live in a remote area or have a large property, consider using a GMRS repeater to extend your network’s range. Repeater placement is crucial, as it can either amplify or cause interference depending on its positioning. A general rule of thumb is to place repeaters at least 1-2 miles away from the base station, ideally at a high point to increase coverage. When using repeaters, ensure your network channels are set correctly to avoid crosstalk and interference.
