I should have thought of it earlier, but I would check out an off-the-shelf preamp. I've heard good things about Ramsey's low-cost preamp kits, such as the PR10 for 2-meters.

I would study the circuit, even buy the kit and change a few value to optimise for your frequency. They are about $15 direct from Ramsey or other outlets.

If you do this, install the preamp as close to the antenna as possilbe, i.e., before the coax. This is because signal loss is generally higher in coax than noise loss.
