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? 73 Tom 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.
