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.



5.8 GHz 25mw airwave - aircraft installation


Recommended Posts

Hi,all

is there any benefit in using an inverted monopole antenna (or inverted skew planar wheel)on the plane, so most of the field radiates downwards??

I'm planning to use just an upward facing patch on the ground - I don't intend to go out far. (LOS with spotter)

I have an airwave 5.8 25mw module I would like to try out on my Twinstar

Thanks all

I have found it much better if the aerial hangs out the bottom on 2.4Ghz and even more so on 5.8Ghz. On my Twinstars the aerial hangs out from the side of the nose and just folds back when it touches the ground. Just dont forget to unfold it again at take off.

Do you plan to fly over yourslf alot? the dipole will have a dead spot directly under the plane but this is minimal unless you are very high.

Thanks Terry, that's a good idea, my ant is just fwd of the tail at present. As you say, flying over myself low blanks out a bit, with dipole on RX/TX but not seriously. I have had better results with 8dbi patch on the RX facing up tho.

I have the ideal plane going together for a tail mounted - down pointing ant, Multiplex Sonic - see how that goes
