433 Mhz antennas for 3Dr radios

If you want to get range, put this http://arrowantennas.com/arrowii/440-7ii.html on a antenna tracker and use the dipole from ebay on the quad.

I had this problem and I buy HAM UHF antennas for PMR radios now I have both to ground module and on air module and the problem gone. PMR LPD G7 G8 G9 MIDLAND ULTRAWEIGHT but little bit expensive but I take a good range. This antenna is only UHF and not VHF like others. And it is lightweight so you can put it in the frame. SY7AQJ

Hi Everyone, I see all of us had issues on 433 telemetry. I myself used the stock antenna and they performed rather poorly. Try this out, it worked for me. Order from team BlackSheep the LRS receiver antenna 433mhz , then order from Foxtech the transmitter LRS whip antenna cost around 19.90 dollars. You can also find this at hobby king , usually out of stock. Now the results are amazing, set your frequency below the 420mhz band and you will get 90% gain even over a mile away.
Good luck.
Don't waste time with those stock 2.4 they came with.

    I use both the TBS 42 and 101 antenna's on mine for about 6 months. Works in my normal range, but not actually done a full range rest yet.
    
    What's the recommended testing approach - the tuning screen in MP, with RSSI and REM_RSSI enabled? At what value does it start to drop out?

    These are all the wrong connectors. Any off the shelf with the correct connection?

        I was always told with antennas never to use connectors/adaptors if you can possibly avoid it, as it's the first port of call for noise/interference. I was looking for ready made antennas with the correct connector already on there, but it seems near on impossible to find.
        
        Which begs the question, why on earth does 3DR use this connector? All the clones seem to use SMA which appears to be a lot more sensible!
