I have an Arkbird Antenna Tracker and I am looking for an directional antenna for 433MHz for the tracker. Do any of you know where to get one? There is a four year old thread about this but no answer that can help me.
I used a couple of 433MHz 6 element yagi antennas for a project a while back, they are identical to these but from a different supplier that does not appear to sell them any more:
They are OK quality. The gain I calculated in my setup was ~8db. They appear to be reasonably directional with significant drop off after +/- 10 degrees or so
Sure, seems like those might work OK…
Nice Yagi there. When google’ing around I find a lot of 433 MHz Yagi-antennas, but how do I know they work with a standard 3DRobotics/3DR 100mW SIK-radio or a 500mW SIK-radio?
(I got 500 meters with two standard 100mW 3DR SIK-radios yesterday between plane and ground, that is good, but need more reliable for RTK Here+ GNSS).
- Scherrer (I got Scherrer RC as well, but this thread is for telemetry for Pixhawk’s): https://hobbyking.com/en_us/433mhz-yagi-ant-reseller.html?___store=en_us
I bought 500mw H King one, I didn´t notice much difference so measured it and was 100 mw
That value Tx-power… shouldnt that be increased to get more power than 100mW?
I am using 100mW standard 3DR SIK-radio and I got 450-500meters on a plane.
But I think I got that Tx-power set to 20.
