A 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

Inverted L antenna per 160 metri
The principle is actually very simple inverted L resonant antenna with a predominance of vertical components particularly advantageous for DX operation
Local QRM/noise reduction
It is not always possible or allowed to tackle the sources of local qrm. What remains is trying to reduce the noise level by means of your antenna system
Loop antenna for shortwave
The small single turn magnetic loop SSTML antenna consists of a single winding inductor, about 3 feet 1 meter in diameter, and a tuning capacitor
Loops, K9AY
A comparison of the real estate needed for four EWEs and the K9AY Loop system shows that the loops need only 1/7 the area of the EWEs, yet they provide the same directional patterns
Magnetic Loop Antenna
The simple remote control was originally designed to operate with a 2.5m portable mag loop for 20-15m and therefore uses batteries
