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 was announced several months ago (March 2021) to allow our members ample 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.



Intersting Ant


Recommended Posts

That 915MHz monopole is an interesting design. The second and third order harmonic trap is a very nice feature. However, it is really meant for very compact designs where more efficient antennas cannot be used due to size. That is to say, it's not that it is better than all the other choices; it just has some advantages, as outlined in the article, when compared to a standard 1/4 wave end-fed vertical monopole.

I think you will find that a good dipole (ducky style) will perform better in our application. If their size is a problem on a small model (at 900Mhz they can be a bit bulky), then you should consider a compact dipole (helical tip design is one example of this).
