I second those comments, Mark. I have ARR mastmount 160 watt preamps for 2 and 440. Huge diff.
I was not surprised that it made a diff on the linear birds. What DID surprise me is HOW MUCH it helped with low passes on the FM birds so that I could work longer distances. What I discovered is that others were hearing me, but I did not hear them until I got the preamp (before the preamp I would call CQ satellite and not hear a response, but I would get an email from the op saying he was calling me. After the preamp, solid copy!)

Hi Jerry,
I cannot say enough good things about the preamps AND the PEOPLE at Advance Receiver Research! They are always personable, quick to ship/repair, and their products are awesome.
I have around 5 of their preamps around the shack right now (okay, four are at the antennas where they belong!). It makes the difference between hearing and not hearing.
In the last few weeks I finally added a 2M mast-mount model at the antenna. I keep kicking myself for not doing it years ago...I can't believe how much better I can hear AO-7 now.
Suggestion---I have found that over the years I tend to "mess around" rather than get what I really want to begin with. In that vein---I don't think you will never regret getting the 160 Watt mast mounted versions:

Models relevant to 2M and 70 cm:
MSP144VDG-160 MSP432VDG-160
Yes, they are an investment of hard earned ca$h. But they're a GREAT investment, if you want to hear...

Jerry,
Like all things in Ham Radio it boils down to how much you want or
have
available to spend :-)
There are lots of folks out there
http://www.advancedreceiver.com
http://www.ssbusa.com/ham.html
http://www.downeastmicrowave.com/
http://www.ramseyelectronics.com
are just a few.
RSGB and ARRL VHF/UHF handbooks all have designs in them as well.

I've seen Preamps mentioned several times now so Who? What? Where? I have not seen them in the AES catalog I got the other day. Can you build one? Need info on them!!
