we have a meetinghouse which is old and only has a coaxial hookup at the pulpit the ysa leader was wondering if there is an adapter that he could use to hook up straight to the projector instead of going through a vhs machine which they do now to make it work.

You need some sort of demodulator. The tuner in a VCR or similar device can do this. If you want something smaller than a VCR, you might consider something like the Ambery LCDT6D or RFDM2.
Questions that can benefit the larger community should be asked in a public forum, not a private message.

You might want to look around the pulpit area. In my chapel there's both a threaded "F" connector as well as a RCA jack. The "F" connector requires the use of a tuner, but the RCA jack just needs a long RCA cable to connect it to the projector.

YMMV.

Take a look at this part. Takes a coax connection (RG6) and converts it to RCA (male) to plug into you projector. I'm assuming that you are just using the coax as a shielded video run from one location to another.

Maybe, not always.

Normally the threaded F connector is a RF connection while the RCA connector is baseband video (or audio as the case may be). The adapter pictured will physically connect, but won't do the necessary transformation of the signals.

It would probably be helpful if we knew what type of signal they wanted to send over the coax be it audio or video and from what it was being injected.

From the connector used, and the fact they are using a VCR to connect it, it seems most likely the signal coming out of the wall is RF. Changing that would require changing the way the system is set up, and may even require a new coax run from the satellite system to the connector as the existing run may have splitters in it.

Since this is in a meetinghouse, and the church tends to follow similar, if not the same setup for each, we have a pretty good idea.

In our Ward House on an older TV that only has the coax input we use a box like this. Dynex WS-007 - RF Modulator Video Converter (RCA / S-Video to Coax). Simple and easy to use and has channel 3/4 select.
