Jason,
I just dug this out of my e-mail stuff. I don't have an answer but as part 
of the UL family you should have access to UL's ICS (International 
Compliance Services) group who routinely track things like this down for 
clients and UL staff. Check with Mike Caruso on the best way to go about 
this (i.e. which office, who to contact, etc.)

Can anyone help me catagorize and determine the appropriate EU directives
and standards for the following product descrption?  Also, does it require
a Notified Body to be involved (witnessed?) and if so can the testing be
done in the states?

Product description:

Five amplifier products requiring CE marking; Low Noise Amplifier and
Diplexer, Controller, HPAA, MHU and MHUI.
These products are used in a 3.5GHz band wireless local loop system which
is essentially a "non-mobile" cellular system used to provide voice and
data communications links to businesses and residences without wire.

Setup:

One config would be the customer provided antenna (Tx/Rx) would be
connected to the MHU, both of which are located outside.  The MHU is, in
turn, connected to the MHUI indoors.  All of this equipment is connected
via coax (48VDC & RS-485 - Tx/Rx)

Another config would be the customer provided antenna (Tx/Rx) would be
connected to a couple of Low Noise Amps and Diplexers all of which is
located outside.  The LNAs and Diplexers are, in turn, connected to the
controller and two HPAAs indoors.  All connections coax.

Info:

HPAA - RCS high power amplifier.  Amplifies RF input signal only - no
modulation or signal generation is done.  Does not interface with the
Public Telephone Network.

MHU - Mast Head Unit.  Amplifies RF signals in the receive and transmit
(Rx/Tx) directions.  Provides a LNA in the Rx path, amp in the Tx path. 
Diplexers put Rx/Tx on one coax.  Does not interface with PTN.

MHUI - Mast Head Unit Interface.  Interfaces the MHU to the customers
communication equipment.  No PTN interface.

It's possible I left out some needed information to assess this equipment
properly, if so please ask.  Any help is greatly appreciated.

Thank you,
