Save your money. You can do just as well by using a passive
transformer to connect the whip to your transmission line.
I actually tried this in an A/B test with the DX Engineering
amplifier. You might start with a Mini-Circuits T16-6 which
will load the antenna with 800 ohms (or if you use RG-6U, 1200
ohms). That will be within a few dB of optimum sensitivity.
Try modeling it on EZNEC and you will see what I mean.
