This is the last of my surplus preamps (sold four already):

It was an old satellite preamp and came with bypass relay box 
(separate) that failed (and not worth fixing).
So you will need a coax relay to use with a transceiver (not supplied)

The preamp was built by Advanced RF Design and uses a ATF device marked "101".
I measured the NF at 1.26 dB with 23.75 dB gain.
Not the lowest NF one can get these days, but will definitely help 
most VHF Radios that have NF upwards of 10-dB.
Housed with NF connectors in 1x2x4.5 inch aluminum box - draws 31ma at 13v

Here is the best part: $20 with free shipping in the USA by priority mail.
Prefer PayPal.
