Long range walkie talkie
A walkie talkie is a transmitter-receiver that allows two or more people connected to the same channel of waves to communicate remotely and in real time. The range is the average maximum distance of ability to listen, to speak audibly and clearly between the interlocutors. Beyond the distance limit, no transmission is possible. a walkie talkie, connected to a public channel PMR 446, has an average range of 5 km. The link is based on the operation of the VHF and UH frequencies. To ensure listening, bringwalkie talkie headset. This accessory is essential.
Long-range walkie talkie and constraints
Are the ranges 30 km, 40 km or more realistic and possible? This is the big question for users. The scope depends on the environment of the positioning of the long-range talkie compared to that of the interlocutor. The waves on Channel PMR 446 propagate in a straight line. When the transmission encounters an obstacle, it will immediately lose quality. These obstacles are the hills, the mountains, the ambient water in the atmosphere of the big trees and the large infrastructures (buildings, houses, bridges). The scope obviously also depends on the technical performance of the walkie talkie and the geographical positioning of the antenna and users.
Long-range walkie talkie and actual distances
You have what the state authorities call "reserved frequencies." In this case, the walkie range can reach more than 50 km. They are long-range, but their use requires special permission. Given the constraints, for a rechargeable talkie on PRM 446, on a flat surface the range ranges from 1 km to 1.7 km. It will be between 400 meters and 900 meters in town. In the middle of the forest, it varies from 400 meters to 700 meters. If the two interlocutors are positioned on the side of two mountains, the range can reach 10 km.
