The reason that I am looking for a locking end is because my microphone preamp/A/D converter(modded Grace V3) is running facing straight up which means that the coax out is facing straght down. As the bag is moved from place to place etc. it seems that the connector can make a less than positive connection which results in the dreaded "no signal". The unit is not particularly convenient to get at one everything is wired up so it's a bit tricky to get at the coax cable to make sure that everything is making proper contact.
I am also looking for a locking end going into the recorder because quite often the bag gets moved, kicked, slid from side to side etc. while running and the more positive a connection that I have on both sides, the better the chances are that I walk away with the entire performance that I am trying to capture. If I was in a studio type environment, no problem as everything can be set up and left as is. Same deal with my playback system, locking ends don't matter much at all as they are generally made once and that's that. I believe that most RCA ends are not designed to be constantly plugged and unplugged and they can get loose after awhile which is what I believe is happening with the Green Hornet that I have been using. Anyways, thanks for the suggestions and I'll gladly accept any more...
