Fabricating Impedance Transformers for Receiving Antenna

Impedance matching transformers with isolated windings, he ferrite core types 43, 73 and 75 had all been suggested

Vertical monopole receiving antenna for
A vertical monopole is easy to set up and provides good reception with a minimal need for space
Waller Flag
The 160-10 meter small lot Waller Flag RX antenna, is working better than ever. Quieter with a slightly better F/B. A good preamp is a must for 160 and some gain is necessary for 80, but no preamp is necessary for 15 thru 40 meters
Yet Another Simple Interferometer YASI
YASI is a simple 20MHz radio interferometer. It uses two antennas, spaced along an East-West baseline and two simple kit receivers, modified so that both receivers share a common Local Oscillator
Antenna in ferrite per ol 10-500 KHz
It is possible to construct a ferrite antenna for LF obtaining good performances with an absolutely negligible expense
