2m Projects - Loop Antennas

Click to enlarge4 Element Cubical Quad 144MHz by MØDAD
When I was living at Gateshead (my last QTH) I found it to be a very poor area for vhf, as I lived at the bottom of a hill surrounded by high buildings, so I built myself a 4 element cubical quad beam. This is my favorite and probably my most successful homebrew antenna I have made.

This is a vertically polarized Broadside and Collinear Array each Loop is a vertically polarized Broadside Array both the right and the left side of the Loop is a bent 1/2 wave dipole working 180 degrees out of phase with the other one and that gives you 4.15dbi of gain.

Een artikel in electron van PA0PEV over een 6 meter deltaloop antenne bracht mij op het idee om een deltaloop voor 2 meter en 70 cm te maken.

From time to time we have written about the small transmitting loop antenna, sometimes called the magnetic loop because its radiation is generated only from its magnetic field (and not any electric field).

VHF Magnetic Loop by ON6MU
A magnetic loop has a very small bandwidth but unsensitive to man made noise. It is much smaller then a conventional antenna for the same frequency and has a gain that can be compared to a quarter wave antenna.
