Arky Bob,

Build your own 1-Transistor Active Antenna

TIP - Mount the Whip {Antenna Element} and
Amplifier outside a Window at 45* like a Flag Pole.

Coax Cable to Radio with Speaker Wire for
power leads to a Switch & Battery near the
SWL Radio.

Better a make your own 2-Transistor Active Antenna

TSE - Instead of a Short (18"~39"} Whip Antenna
Use a Mini 12"16" Hula-Hoop as a Frame for a
piece of 300 Ohm Twin-Lead [TL] taped all the way
around it. On one end {left-side} use one wire
of the TL going CW, and on the other end {right-side}
use the other wire of the TL going CCW. This gives
you two parallel wires that are equal and opposite
that act as a circular-dipole. This Mini-Loop-Dipole
Antenna Element can then be both 'rotated' and
'positioned' to reduce your local noise pick-up.

hope this helps a 'tiny-tenna' itty-bitty - iane ~ RHF
