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.

darn new guy again, Connector FAQ / WIKI?

Recommended Posts

So, I was building the rc-cam4 system rc antenna (www.rc-cam.com/rc-cam4b.htm) using a piece of coax I found off an old 2.4ghz "Spektrum" RC radio transmitter antenna. I test fit everything before I went at it with the cutting instruments. After turtle necking the ground shield, I grabbed the ohm meter to check my work, and crud, the female threaded section doesn't have a male center post.

So, I thought I had an SMA connector on the coax, but I guess they make more than one version?

Is there a Wiki / Faq / or something detailing a simple way for a darn new guy like me to navigate the connector waters?

Thanks again,


Oh wait, looks like I got a "Reverse Polarity" connecter, which really isn't "reversed" it just has different center pin orientations.

So, knowing that, can I just fab a "male to male" center pin to go between the two, or should I start scrounging for another piece of coax with the proper end on in?

You can give it a try if you have young eyes & steady hands, but at these frequencies, I'd look for a piece of coax with the proper connector. Those darn little connectors are harder than Hades to work on.
