splitter for composite video

I'm assembling the pieces to put an "eye in the sky" via a 2.4GHz mini-cam
in a radio control model airplane.
The 2.4GHz receiver has composite a/v RCA outputs. The video will be going
to a camcorder (old Hi-8 with only a viewfinder) and a new mobile 5.6" LCD
monitor. I've used a simple Y on audio connections in the past, no problem,
but never tried it on video. Will this degrade the signal substantially,
and I should be looking for a distribution amp/splitter? Not a big
expenditure, but if it's necessary I'd like to get it ordered ahead of
time.... TIA

My experience has been, you can split once with little or no loss.
Split it twice and you've lost it

Composite video is traditionally terminated in 75ohms, and simply
paralleling two inputs *can* result in the incorrect levels. The correct
way is to only terminate the end device and 'bridge' the line with the
other(s) at high impedance. However many devices now auto terminate or
have AGC circuits which compensate - at least in part.

Maxim and others make cheap video buffer chips to drive multiple
