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.

I've went and ordered up a 900mhz spy camera setup(cheapo) and its stating 902-928mhz. I'm presuming its a single channel and because of the tuning knob, my frequency will vary. Any suggestion on the scaling factor for this one?

Thanks in adavance.

It's anyone's guess; Maybe aim for something around 910MHz.

A/V Rx's with a tuning knob are usually marginal performing China models. So keep in mind that if you have poor results then it might not be due to the GP Patch.

Thanks for the info. I received the unit today. I've got it dialed in fairly well. I'm only hoping for inddor range around 200' feet or so for indoor FPV. A golf dome would be the largest and 6 BB courts most of the time. Thanks again

If you mean you want to solder a simple monopole antenna onto a cheap Hong Kong Tx, then a 1/4 wave element would be 3.08" long. I suggest making it 2X longer and then carefully trim it down for best range.

However, if you have a quality made Tx that has an SMA on it, then I suggest you use a commercially made 2-3dBi dipole. These are usually about $10-15 and are sold at all the popular FPV shops.
