Hi,
I know those RF to rca video boxes for tv's that don't have composite video and all..... but is there a RCA to RF box or cable? I would want to connect my antenna to my panel, but it only takes rca or vga.... any thoughts? Thanks in advance.🙂

You need a modulator.
They're available quite chaply from shops specialising in home cinema, etc.
Alternatively, you can get the actual modulator 'chassis' fom component suppiers, and build your own PSU, case etc.
The third possibility is to use an ordinary VCR - it's internal modulator will do the job for you, or if you have an old VCR you could carefully remove the relevant panels and case them up neatly.
EDIT:
Re-reading your post, I think perhaps you want RF in - baseband out. Same applies re using a VCR, though - use its internal tuner and video out sockets. Stand-alone tuners are available, but are rather less common than modulators.

VGA versus RCA composite video
If you have a high resolution LCD panel, it will look a lot better using the VGA input. RCA jack composite video is bandwidth-limited to match broadcast TV: About 320 by 480 effectively. Even the lowest resolution VGA should be 640 by 480. Maybe your panel can handle even higher resolution than that. You might also have video format mismatch problems, if your VCR puts out PAL or SECAM format, and your LCD panel expects NTSC format.
VGA formats are universal: Same all over the world, so no mismatches if you use the VGA input. You can buy a nice video-to-VGA converter for less than $100 US. I have one I paid $65 US, and it accepts cable RF, S-Video, or NTSC composite and generates VGA at 640 by 480, 800 by 600, 1024 by 768, or 1280 by 1024. If you want to view video from a device that has S-Video output, you should use it. It is much better than composite. If you have SCART output, see if it has S-Video in the connector. They might just label the signals "luminance", "chroma", and "sync".
Component video or digital video are even better: If you have a device (maybe a high-end DVD player) that can output one of these formats, you can get a video-to-VGA converter that accepts it as the input. There are more than one component video formats. If you buy one of these, make sure it will accept the exact format of your video device.

I dont know what quality you get from your tv signal, but with a proper deinterlacer, I get 754x480. It looks about as good (maybe abit less) at 640x480 too, but not that great at 320x480. I actually think that these panels have pretty bad deinterlacing so 640x240 sounds more promising, lol.
I suggest that you use a tv tuner card for scaling the video
I use an older MSI TV@nywhere tv tuner, and DScaler software.
I run my TV signal on my monitor at 754x480, 60fps, progressive scan, upscaled to 1024x768, or 1280x960, or even widescreen (squish to anamorphic mode, or cut off the top/bottom) at 1280x720. When I plug a dvd player through Svideo, it looks almost as good as running it direct on the dvd drive. (btw, svideo is much much better than composite)

That is probably because OHP projection panels are old technology. A TV tuner card in a high performance computer will do much better. If you have a good DVD player drive in that computer, and you also want to play games using the projector, then that is the way to go. It will all go into the panel's VGA input so you will get the very best possible picture from the panel.
If you don't want to have your computer tied up with your projector, then get a video-to-VGA converter. It will also give you a great picture, and you can get one that fits your needs exactly.
Forget about the composite input on your panel!
(Caveat: I work for Conexant Semiconductor, who makes TV tuner chips, among a lot of other things.)
