I've heard nothing but good things about ARR gear. However, you are
probably correct that most situations will not find this preamp to be
useful.

How about following this preamp with a passive splitter to make a low
noise multicoupler?

For One and All,

Is anyone using a Advanced Receiver Research (AR2)
High Performance "Receive Only" Broadband Pre-Amplifier ?
http://groups.yahoo.com/group/Shortw...a/message/6654

Features:
* Low Noise Figure
* High Immunity to Overload
* Completely Shielded
* Suitable for mast/tower mounting
* Small Size
* Rugged low profile custom enclosure

Claim is that these Broadband Pre-Amplifiers use a low noise
figure, heavy-duty bipolar transistor in a multiple feedback
circuit to obtain essentially flat performance characteristics
across the frequency range.

Are you using the Pre-Amplifier In-Doors in the Shack ?

Or - OutSide the House at/near the Antenna to Coax Cable
Feed-in-Line junction.


i want to know ~ RHF

How would such a device help anywhere but on a DXpedition where the
background noise is very low?

Yeah,but let me post a question or something about Shortwave and or
AM/MW and I hardly ever get a whimper from anybody.Check on back in this
news group as far as you can and tell me I am lieing.

You have a point about using the amp for a remote antenna. However, I'm
not sure you want 50 ohms impedance on the input.

I haven't check the price of the amp, but you should compare it to the
Wellbrook ALA100, which could be used in the same application (remote
antenna), plus it is designed strictly for loop antenna applications.
It also floats the antenna above ground, i.e. the input is balanced.
