I'm a CS college student working on the flight computer of my Rocketry Club's rocket. My flight computer has a 915MHz radio transceiver, and it needs to transmit data to my computer with another radio receiver on the ground. The rocket at the maximum height will be at least 10,000 feet (3048 meters) away from the ground radio, and probably no more than +2,000 feet of that. (Specifically, I'm using an Arduino paired with an Adafruit RFM69HCW @915MHz radio breakout board for both the flight and ground computers)
Both the ground and rocket radios have SMA connectors. I have not yet figured out how to deal with the antenna situation.
I don't know too much about amateur radios and whatnot, so I was wondering if anyone had a suggestion for an antenna that could handle the needed range, and if not, suggestions on what/how to build an antenna for the radios to handle my required range.
Thanks so much in advance!
