The SCART input supports all three methods of connection, these can be:

1.  RF input, the signal which comes from the antenna is RF and this is the
    output from a UHF modulator.
2.  Composite video. This is the picture and sync signals as extracted from 
    an RF signal or as the "video" output from some VCRs.
3.  RGB + sync. This is the three picture signals plus a sync signal.

The RGB has the best quality, CompSync next and RF third. 

The problem with SCART inputs is that the interface can support all three
types of system. There are some SCART inputs which support RF and Composite
but dont have the RGB connected. The only way to find out is to check the 
manual for the TV. Generally they list the inputs, if the RGB and SYNC aren't
mentioned then the TV wont accpet them.

The composite input is also the sync input for RGB signals. Some TV's also
require the sync and fast blanking signals to be connected together. The old
SONY monitors have this problem, (but a great picture).

The only way to be sure is to test it out.

Using the newer modulators it is fairly ok and will just about support 80 col
working. The older ones were pretty fuzzy and only worked at 60 col. If you
do ues a modulator they also have a Composite output which is better than the 
standard RF.
