Limited Space Antennas The Small Transmitting Loop Antenna
The AEA IsoLoop HF Antenna was an antenna I used off the balcony in a Chicago high-rise

Magnet -loop for 80M - 40M
Detail of coupling loop and experimental capacitor theoretically 128 pF/3.2 kV for 80m, 14 pF/5.6 kV for 40m at 50 W

Magnetic antenna for ULF
All the cores are connected in series with a centre connection after 20 turns, resulting in a rectangular coil of 20 + 20 turns

Magnetic Loop Aerial for 20m
The construction of magnetic loop antennas. HF bands we needed an antenna design that was suitable for use indoors or on a balcony

50 MHz preamp Gain 26dB with the BFG135

50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
