Active 3-30 MHz Hula-Loop Antenna for Shortwave
Home-made antennas can greatly improve the performance of AM and FM radios, short-wave receivers, and scanners

Active Ferrite Rod Antenna
Matti OH7SV did some tests to find out if Active Ferrite Rod antenna can be build for 80 / 40 Meter ham band reception. Matti's experiments are documented here

Active Antenna AA-7 HF/VHF/UHF, 3-3000MHz, Antenna booster
is a small antenna going through an RF preamplifier to a receiver

Shortwave Portable Receivers
shortwave portable radio, portable shortwave receiver, world band radio, worldband

An easy vlf loop 200Hz-20kHz reception without transformers
the loop antenna is easy to build but the preamplifier has a lot of active components many gain stages, much noise
