List, I would suggest a noise budget calculation for a EMC bandwidth of 120 kHz before you proceed. You may need to consider mounting the pre-amp on the test (receiving) antenna and in such case consider the possibility of ESD damage during set up.

These had around 20dB of gain which was sufficient at 3 or 1 meter for most frequencies between 1 - 18 GHz. The exact model that we used has been discontinued though and I am unsure if a replacement has been designed. I believe the cost for these preamps was between $1k - $3k, so they were pretty cheap if you are handy enough to build your own box to protect/power it.
