We have added this Sain Sonic ARPS radio. Compact with GPS built in.
Rob, KC6TYD use a slightly different payload. In addition to the rubber duck antenna he deploys a folding J-Pole from and ankle pouch and use an antenna switch to switch between the two. He also incorporates Bluetooth headset in his helmet paired to a PTT switch so there is no need for a speaker mic.
Our HF jumps incorporate both FM and HF so there is a lot of payload.
Our air-to-ground live video consists of a GoPro camera and a 2 watt 5.8GHz transmitter. The transmitter is a Black Mamba with a circular polarized antenna. The transmitter is attached to the jumpers foot and a composite cable runs up to the GoPro mounted on the jumpers radio vest.
To Receive the transmitting signal we use this Diversity receiver.
The APRS, video transmitter, and FT-817 are all power by a Bioenno LeFePO4 battery. This 3Ah battery is compact but still provides enough power to last the whole day.
Mikey, NE6RD, built a weather station that sends data directly to a laptop making wind speed and direction updates a snap.
Over the years we have created quite the antenna farm. Recently Rob, KC6TYD, created some nifty mounts for the Ed Fong J-Poles we use. https://youtu.be/MNyt8JpdvPE
