3DR Telemetry Antenna 915Mhz

The 'exactly 915mhz dipole antenna' includes casing for 2 antennas, receiver + transmitter. (This product requires basic soldering and DIY skills) http://diydrones.com/forum/topics/new-3dr-telemetry-antenna To increase telemetry range our designer made a half wave dipole antenna for himself as per IBcrazy’s guides for the 915mhz. Many stock antenna from non 3DR sources have no markings or even 2.4ghz written on them.

The Dipole was great, but required caliper measurements and gluing/mocking up antenna tube casing supports, ensuring 180degrees, didn't look sexy so on.

This is why the “exactly 915mhz dipole antenna” was created. It’s a very light weight antenna (Jackless and around 6g) design which also is a template for the precise length of the antenna trimming, and ensure it’s a straight 90degree bend to form 180degrees.

Available in a range of colours.

Instructions:

1. Remove PCB antenna jack
2. Solder on 2 wires as per image. Around 10cm (will be trimmed later)
3. Clip on bottom half of antenna shell and fit wires into the grooves
4. Push in top half and antenna shell and secure with method of your choice (tight fit design, it stays in place without extra tie, but I used heat shrink. CAREFUL if using heat shrink, the material warps if heat gun temp is too high or used for too long)
5. Trim wires.
VOILA it’s now for 915mhz exactly!
