How does a collinear antenna work?
In geometry, a set of points are collinear to each other if they lie on a single line. In telecommunications, when two or more dipole antennas are vertically stacked in such a way that their corresponding elements are parallel and collinear with each other, it is called a collinear antenna array.
How big is a 2m VHF collinear antenna?
This page is the second part of my VHF Collinear antenna project with matching-system for 2 dipoles model (Gain = 5.15 DBi). This is also a nice ham project, een small antenna for 2m and 70cm, after using it you can roll-up the antenna, very nice on holidays… I invented a similar system, but completely made of RG58 coax.
