[size=14.6667px]Hi:
[size=14.6667px]so, while we are dealing with an HDMI output issue (waiting for DJI response), we are fine tuning our "ground station" for live feed to OB trucks:
[size=14.6667px]We need to improve our radio signal. The slave RC must be close to the OB truck, and sometimes not in the best spot to use the stock antennas fixed to the RC. We are planning to connect two high gain dual band omnidirectional antennas and mount them in a high pole/mast. Are any of you using something like this? Wich brand of antenna/cable type/cable max. lenght are you using?
[size=14.6667px]We are not aiming for extreme range. The farthest we can go is 500m, but we need the signal to be solid at every moment. And as the video signal goes straight to the slave RC, we need to improve that signal, is that right? (is not a problem if in the master RC we receive a frozen frame from time to time).
[size=14.6667px]If you have some photos of your setup it would be great
[size=14.6667px]Thanks!!

hi Ale, the original antenna should be fine with 500m, if you really want to extend the range , you can try to use tinfoil surface surround half the antenna to make it as a reflector, this may help you to make the RC's antenna from omnidirectional to directional

Hi Jackyyy!
Yes, most of the time we are fine with the stock antenna. But we want to make the signal really solid, with no microcuts at all. It´s for live feed. That´s why we are planning to set the antenna high. Far from people or things crossing, etc.
I have seen some ground stations with antennas in a mast, so I was curious about brands/models, etc.
Thanks!
