Thanks, Ed, for pointing out this amp - truly remarkable specs - especially that 0.8 dB NF! I also like the fact the company can tailer the frequency response.
For those who may need only 20 dB gain, you might consider a Mini-Circuits ZX60-3018G-S+ module for general troubleshooting. I've been using this for my seminars and troubleshooting gigs and it works well. At only $50, it's a bargain. I have a picture and additional details on my Web. http://www.emc-seminars.com/Tech_Topics/Tech_Topics.html.

I recently bought a Nuwaves HILNAV1-C preamplifier that is customized for the 30 MHz to 1000 MHz range. (The standard HILNAV1 is half the price, but is rated only for 50 MHz to 1 GHz.) I characterized the gain and found that I got about 45 dB from 30 MHz to 100 MHz, with a nearly linear drop off to 35 dB at 1000 MHz. The great part is that all this gain also has a Noise Figure of less than 0.8 dB! The preamp will accept up to about -30 dBm before it starts saturating, and even 0 dBm doesn't cause spurious products. See http://www.nuwaves.com If you need a really hot preamp to help the sensitivity of you biconical or log periodic, this unit is a great choice. (I set mine up with a couple of Bias-T's, so that I could power the amp remotely through the coax and still place it at the antenna. I have some data sheets and construction photos if anyone is interested.) Total cost was $550 for the preamp and $150 for a couple of Mini Circuits Bias-T's, plus a couple of metal project boxes and a wall-wart from the junk pile. It beats the performance of my HP-8447A by 10 dB.
