    Proper Orientation New Diamond Antenna

    What is the proper orientation for the antenna? I would assume broadside towards the aircraft? Looking at the pattern for the antenna was not sure.

    Different antenna. The one you show is dipole and that is correct. I have dipole on the quad. Here is the antenna I just got.

    Ok I'll stick my neck out and suggest that it looks an awful lot like a Moxon Rectangle to me and if so, that means it has a wide angle of response in front of you (about 180 degrees) and a poor response behind you, so try and point it at the aircraft, but you don't have to be really picky about it.

    Proper Orientation New Diamond Antenna

    Thanks!!!!

    That is sort of what I thought. Will be interesting setup. I am vertical off back of the quad.

    You are welcome - hopefully that info will make it to the next rev of the Crossfire documentation. When you get a chance to test it please let me know how it works for you. I get some weird RSSI discrepancies sometimes. The Taranis will complain about RSSI low for just a split second but the OSD shows >90. That might be due to the lag in telemetry and I missed it on the OSD. So far never seen a failsafe but I'm only going 1,500 feet out. Im just using the stock Crossfire TX antenna and an Immortal T on the copter. Hope you get some good flying weather down there this weekend. It's a voltage sagging mess up here in Dallas.

    Proper Orientation New Diamond Antenna

    I have just been using the whip Diamond antenna and I have been using EzUHF since I started. I have never had any issues so is hard to change, but the most I had been flying out was .5 to .75 miles.

    I reconfigured the quad (a QAV540G) so could put on a 10000 MAh battery, converted over to 1.3 GHz for video, am using 11-in. blades and programmed in a 1 mile flight to see how things worked. (Have Vector controller. )

    There were no issues (other than an issue switching to my GoPro video for camera aiming) including frequency interference which I was worried about. Clear as a bell. I set up the flight to test out video (while way outside Houston the location has a few transmission towers around and we all see weird interference on 5.8. ) The video worked very well. The battery drain and times involved indicate I should easily be able to go out 4 miles and return. I will be staging to that distance as soon as weather gets a little better. Right now a lot colder than usual. I just want to try and insure I have a lot of room for error! Is why new antenna looked good. I am using a Taranis.
