LOL!

Kidding aside, KA4SEY, I use an active whip in the backyard and the
receiver currently in use is a Kenwood TS-890, which I purchased last year.
Prior to that, I used an ICOM R-75 and a Winradio SDR, which both performed
well.

The trick to using active whips for LF reception is you have to get them
physically away from noise sources, the biggest of which, most of the time,
is the very house you live in. Common mode chokes on the coax out to the
antenna can also help. For a receiver, you want one that is sensitive at
LF, and has good IMD characteristics. Also helpful are a frequency readout
to 1Hz, and narrow CW filters (if you plan to hunt beacons aurally).

In the past I have used, with success, an active loop and my old amateur
radio dipole with a tuner that I copied from an old Burhans article. I
didn't like having to fool with a rotator, and the ham dipole picked up a
lot of noise at my QTH.

Do you have anything to receive LF with? If you live near beacon KE, that
might be problematic.
