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.

Band Pass Filters for 900 MHZ video, Is it worth it ?

Recommended Posts

Here are some very cute little band pass filters that you can buy for just about any frequency you want ! I am wondering if one of these little guys might help me or not. I have a DEMI 26 dBI receive preamp on a standard 900 mhz video receiver, but it really seems to have no effect on sensitivity and video quality. Someone suggested that the receiver might be desensitizing due to strong out of band signals with this preamp, or even without it ! Does anyone here thinik that it would be worth the 40 bucks each to put these on my video recievers ? I fly in rual areas, but am not that far from the city either, and there are cell towers around. I would like to give these a try, but I dont want to spend 80 bucks on nothing but insertion loss if they would not have any positive effect. What do you guys think ?

Here is the Preamp, I dont really notice a difference using it though, video noise with weak signal seems about the same at long distance bith with or without it. Some have suggested I might be overwelming the receiver with out of band signals with it, which is why I am now considering a band pass filter.

I agree thats a lot, unless you have a very long co-ax down lead. I have found in the past that even with a long down lead it is very easy to have too much gain, it seems most receivers have a sweet spot for signal where they work best. Too much gain swamps the receiver and the signal is just as bad as too little signal. An adjustable attenuator is best so that you can tweek it while watching.

The band pass filter may help if you if you have high power out of band transmitters near by, even your own R/C TX.

I wound think they are best on the TX side though and may kill interference to the R/C RX or GPS.
