Attention: RC-CAM.com will be closing down August 2021.

The RC-Cam.com forum was the very first online community dedicated to the advancement of wireless video cameras on radio controlled (R/C) models. This is now called "FPV" (First Person View). We are proud of the contributions that our members have made to the FPV hobby.

We've seen significant changes over the last twenty years. Initially there were a lot of eager R/C hobbyist that built their own video systems. Allowing these creative individuals to share their work was the purpose of this site. Now the FPV market is flooded with low cost systems; Sadly DiY FPV video projects are now rarely discussed.

RC-CAM.com (main site and forum) will be closing down August 2021. This is being announced now (March 2021) so that everyone has time to download any information that is important to them. After the site is shutdown the information will no longer be available here.

We appreciate every member's involvement with advancing the FPV hobby. It is indeed sad to say goodbye to all our online friends. Be safe and stay healthy.

GP Patch for super long distances

Recommended Posts

I am looking build a 900MHz GP Patch antenna and connect to a 1W radio modem (AC4490-1000M). This is to talk to a GPS sent up in a high altitude balloon. In theory the distance could be 25-35 miles. I would have a GP Patch on the ground as well for receiving. Any reason to think the GP Patch could not handle this?

I have read about people using a L-com patch panel antenna to do this with success. And the GP Patch seems to have about the same specs (50ohms, ~8dBi). But not sure if I'm overlooking something.

For situations like this where both antennas will pretty much always face each other but will turn, I think I'd rather use circularly polarised antennas.

I'd worry more about having a 1W 900MHz TX right next to a GPS receiver though. That's rather likely to jam the GPS.
