 ====== Repeaters ====== ====== Repeaters ======
-{{ :links:meshcore:meshcore1.png?300|}} +  * Install a repeater like the //SenseCAP Solar Node P1-Pro// from [[https://www.seeedstudio.com/SenseCAP-Solar-Node-P1-Pro-for-Meshtastic-LoRa-p-6412.html|Seeed Studio]] or [[https://ca.robotshop.com/products/sensecap-solar-node-p1-pro-for-meshtastic-w-gps-battery |RobotShop]] 
-As mentioned in the [[#part1 |first part]], repeaters are used to extend the range of companions. With radios, the range roughly depends on three factors: +  * Use an antenna like:
-  * The antenna characteristics of **both** radios, their heights above the ground, and the line of sight between them. +
-  * The transmitting power of **both** radios. +
-  * The frequency used. +
- +
-Let's highlight here that it doesn't make sense to talk about the range of //one// radio.  For example, I might be able to reach Bob at a maximum distance of 1 km, while reaching Alice 2 km away.  That's because Alice might have a better antenna or be higher up than Bob.  If one person improves their antenna, height, or line of sight, it helps everyone communicating with them. +
- +
-That's not so with power.  If Bob increases his power, everyone will hear him better, but that won't help him hear anyone else better.  It's like if two people on opposite sides of a football field tried to talk to each other: one with a megaphone, and one without. +
- +
-As a rule of thumb, everyone should use roughly the same power, and focus on improving their antenna, line of sight, and height. +
- +
-With that in mind, to be effective, a repeater should have a good antenna, be as high as possible, and have a clear line of sight to other repeaters and companions. +

-====== Equipment ====== +

-  * A repeater like the //SenseCAP Solar Node P1-Pro// can be purchased from [[https://www.seeedstudio.com/SenseCAP-Solar-Node-P1-Pro-for-Meshtastic-LoRa-p-6412.html|Seeed Studio]] or [[https://ca.robotshop.com/products/sensecap-solar-node-p1-pro-for-meshtastic-w-gps-battery |RobotShop]] +
-  * The antenna can be upgraded with one like:+
