Hello Ed
Here is one with a five star review

I do not know what the IP3 is - a quick email to K7TJR might get that info
pretty quick.

Subject: Topband: Few questions about RX Ant preamps
Looking at the W7IUV preamp kit sold here
http://www.mtmscientific.com/preamp.html
<http://www.mtmscientific.com/preamp.html>
I would like to place the preamp at the RX Antenna (YCCC 9 Circle )
because of the 450 Ft of RG6 from ant to shack . The W7IUV preamp is 50
ohm so not sure if it's ok to use at the Ant? Or if I'll be just fine
using the preamp in the shack after the 75 to 50 Ohm transformer ?
Can the input and output be easily changed from 50 to 75 Ohm ?
Does anyone sell a RX Preamp with 75 Ohm in/ output ? Need IP3 of 30dbm
or better .. I know DXE has a nice preamp but it's designed to add other
boards that I don't need .
Thanks Ed N5DG
