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“
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 (by VK3YE)
Free windows program to calculate magnetic loop antenna.This small loop antenna calculator allow to determine capacitance and voltage based on Loop circumference, desired resonant frequency, conductor diameter and the operating power
