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.

  1. I have just build the GP Patch antenna to the exact specs on the site and used the roof flashing for the plates, when i checked the input impedance it wasnt 50 ohms. At 1.2 GHz it was 29ohms and at 2.4 GHz it was slightly lower but with a higer capacitive impedance. The antenna actually worked at 1.2 GHz much better than for the listed 2.4 GHz. Testing was done on an antenna analyzer piece of equipment used in the electrical engineering department of the university i attend. Has anyone had any problems matching the impedance on the patch antennas they have build? Thanks
