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.

Why is the connector offset on the GP?

The RF feedpoint position determines the impedance of the antenna. It is a VERY critical placement.

The polarization of the antenna is determined by which end of the antenna is at the top. Tests at the field will help determine which way is best for you. But, I suggest that you start with the end that is marked "Top Front" and go from there.

Ok, thanx Mr RC CAM. I was wondering how that worked. I didn't realise that there was a top or bottom to the GP Patch. I just figured that your directions were for building the antenna and not for it's actual operation. I was thinking about trying it upside down on my helmet receiver combo so that it wouldn't stick up so far. Thanx once again

The GPP antenna is nearly symmetrical in each plane (just consider it to be a non-issue). Vert vs. Horiz Polarization is at 90 degrees.

Usual installations will want "Top" to be at the top. Some will work better with Top rotated 90 degrees. This is discussed in the project page.
