Invisible DX Antenna for the Low Bands
This paper describes a multi-band DX antenna for the 160m-40m amateur radio bands

Receiving loop aerials for 1.8 MHz
Localised noise in the receiver can be reduced by using a small loop aerial. Shielded coax loops, unshielded loops and ferrite rod loops for 1.8 Mhz have been compared here. Best peformance has been achieved with with 6 & 1/2 turns unshielded on a 0.8 metre frame and connected via a balanced interface amplifie

Dual-Flag Receive Antenna
The antenna is made up of two rectangles 30-feet long by 20-feet tall

Un'antenna in ferrite per 40/80 metri
The simple simple design includes two BFX89, one potentiometer and a variable air condenser, plus a handful of resistors and capacitors
