Preamp and AGC for LFRX?

Hello!

I’ve ordered a USRP1 and LFRX. I was wondering if anyone knows where I
could buy an RF frontend (consisting of preamp and automatic gain
control) to accompany the LFRX?

I’m interested in playing with different parts of the spectrum from DC
up a few MHz.

Would really appreciate any help as I’m new to this area - Josh
