    Hey everyone. I'm thinking about maybe replacing my stock transmitter 5.8 antenna with something with a little more gain. I don't want to get into boosters or anything. Does anybody know the gain (in db) of the stock antenna? I have successfully flown out to 1800' out at 370' high. This was my best distance. I often have weak signal issues with the 5.8 at around 500' depending on antenna position and the quads orientation. 2.4 has never dropped or become weak. Thoughts?

    Try using a Windsurfer. You can buy one or make your own. Just make sure you get the right one for 5.8.

    I will be building a windsurfer shortly. Does anybody know the specs of the stock 5.8 antenna?

    I believe this is transmitter output, not antenna gain. This however is useful information, not sure how I didn't catch this earlier. Thanks for the post.

    I don't believe the stock is 27dbi if it really is then its pathetic .because then you will be getting 5km range. With no range problem.

    Because if the ARGtek antenna is a 7dbi people are getting about 1km.

    Just my 2c. I think the stock antenna is only 3dbi .

    I just purchased 2x 11dbi 2.4ghz antenna to replace the stock just trying to source a 11dbi 5.8ghz.

    After looking at the DJI site, the 2.4 transmitter is 27 dbm and the 5.8 transmitter is 19dbm. I would expect somewhere around 3 dbi for the 5.8 antenna. I'm just going to try and find a small 5.8 antenna with a high dbi rating. In the mean time, I built a windsurfer. I will post my results in the main p3s discussion page.

    It's cool buddy. I'm lookng forward to test my 11dbi 2.4ghz antenna its not gona give me range but I'm hoping some good wifi signal downloading.

    EBay and aliexpress have 11dbi 5.8ghz antenna for sale.


    5.8ghz = for range. Looking to increase range increase the 5.8ghz antenna

    2.4ghz = wifi signal.

    Just extra for information if a newbie has to read our posts
