We already presented in a previous articles Seven Delta Loops antennas for 7 MHz, and even 7 MHz Yagi antennas
Here we have reviewed 7 small loop antenna for the 40 meters band.
Loop Antenna Design
“Small Loop antennas also known as Magnetic loop antennas are radio antenna made in a loop shape, and behaves electrically as a coil with a small radiation resistance. These antennas are very small if compared to the full wavelength. Often used as receiving aerials can be used as transmitting antennas“
Small Loop Antennas for 7 MHz
Able to cover all frequencies between 3.5 and about 10 MHz, the loop described here is directional, does not require a radial system, and stands just 1.8 metres tall. The antenna can be put together in a short time and is cheap by Peter Parker VK3YE ex VK1PK
A coaxial cable tuneable magnetic loop antenna for 7MHz. This experimental antenna does not require a tuning capacitor
Evolution of a project of a small magnetic loop resonating from 80 to 40 meters
A simple multi-band magnetic loop antenna designed for 20, 30 and 40 metres. For its size, the performance of the antenna always astounds me, although it is never going to replace a Yagi
