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 Antenna Material options


Recommended Posts

Hi Guys,

I built a GP Antenna for 868 Mhz, works great, but heres the problem. The antenna is pretty big, and we used thin Zinc ( Galvanised ) plated steel sheets. The result was a sort of flip flop antenna, with no strength at all! Heres what I want to do now, The reason for the thread here is to find out if what I'm doing is OK. I want to build the antenna using 1.6mm Copper clad PCB material. The construction remains the same, the spacing between the copper layers remains the same. The dielectric is still air. Will this work OK? Can I also have small plastic ( poly propylene tube ) spacers and plastic nuts and bolts holding the GP antenna together?

What is the best suited antenna for LOS range? Lets say video at 2.4ghz. Will a Helical antenna work best?

-Thanks,

Uttam

FR4 is not RF passive. Laminates like Teflon and ceramic are normally associated with microwave designs. You may be totally happy with your FR4 solution, but it is hard to predict the affect on the design without measuring it. If it was me, I would just use a slightly thicker metal material for the driven element.
