David,

You don't need a top hat for a RX only antenna.

Not knowing anything about the hytower....if it is base insulated from
ground, I'm sure you can use it for LF RX with the right combination of
L/C. For RX, the L doesn't have to be a huge coil like it would be for
transmitting....simple slug tuned inductors or fixed values with a switch
to select should work.

There are easier solutions to receive LF, however. Small loops and e-probe
active antennas come to mind.
