I want to increase the range of my telemetry module. I am using Holybro 915mhz 100mw telemetry. According to the Holybro official site description, I can increase Holybro Telemetry range up to km by using a patch antenna. I am confuse that what type of i will use in there. I post the pictures of antenna please tell me, is it perfect for it?? 

1st one is Hubsan H501S H502S 5.8G 14dBi FPV Enhanced Range Modification Antenna Kit. And the panel

2nd one is 5.8G 14dBi High Gain Directional Patch Antenna Panel Antenna RP-SMA /SMA FPV

3rd one is 5.8G 14DBI High Gain Mushroom FPV Antenna RP-SMA For Receiver RX

4th one is 5.8G Image Transmission 9dB High Gain Omni-directional Antenna FPV Image Transmitting Antenna SMA Joint Remote Process

Can I use it in my telemetry??? 

Please reply anyone please

This is just a blog and people will only reply if and only if someone knows about your question. Be patient when posting in public forums.
And do not create multiple threads.

Coming to your question:
Your telemetry modules operate at 915Mhz frequency and the pictures of antennas you posted are 5.8Ghz. You should not use these antennas with your telemetry modules. Chances are likely to decrease the range and also damage the transmitter.

Sorry sorry 😞😟
And thanks for response. Then please suggest me a patch antenna that I can use there. Please see that....

Please please 🙏 tell me what type of patch antenna I will use in my holybro 915mhz 100mw telemetry. In the manual of holybro they are asking that increase up to km by using patch antenna.
But in the market patch antenna available for fpv video transmitter. So I am confused, please. Please tell me what type of patch antenna I will use in here.

Please please 🙏 reply me

Not sure. sometimes these may work. (Just a thought) Remember , mobile phones work in that frequency. 433mhz may be better.

Thanks for that. I will try it.

Though my normal antenna is 2dbi like that, I want more dbi antenna for it. But one of my ideas was made from your suggestion. thanks

for 915 mhs you can use tbs/frsky antennas it should increase the range

Thanks many many thanks. 🙂☺️

welcome happy flying
