I use a BC-780XLT and an Icom R-7000 coupled together with a
Stridesberg two port passive multicoupler.

This setup works well except the coupler sucks about 4 dB out of the
signal.

Since many of my targets are already weak, I'm looking to replace the
4 dB.

Wonder if anyone has experience using the GRE 3001 preamp at LOW GAIN
settings

I've seen all sorts of horror stories about pre-amps, and no one
comments on the gain setting they used. I suspect many ran the things
on the max 20dB setting.

All I want to do is overcome the losses in the coupler (without having
to buy the 4 port active coupler as these things are pricey).

Comments anyone?

I use a GRE Preamp but only for a specialzed use, to receive MilSats
using a Yagi cut just for that band. For this purpose it works great,
even at 20 dB gain. However the same GRE Pre amp on a wide band ant
(even with gain set to minimum) has caused me both FM overload and
increased interference problems (and I'm not real near an transmitters).

So I do like the GRE Preamp but only when on an antenna which will only
receive the band you're interested in.

I've been using Stridsburg multicouples for some time, however I only
use the amplified modeles. They simply are GREAT! I have 2 of the 4
port versions and an 8 port version for VHF/UHF. Soon I'll be buying
another VHF/UHF 8 port model as well as a 4 port HF model. But I always
suggest spending the extra $$ and get the active version, you'll be
happier in the long run.

As a side note, if you need to you can cascade two multicouplers
together with no adverse effects. I do this often. Stridesburg has
suggested not to cascade more than two units, I've only ever done two
units and it works great, most of what I monitor are MilAir signals most
of which are well over 100 - 200 miles away on UHF.
