0 berkinet Posted December 28, 2018 Report Share Posted December 28, 2018 I had a teacher who used to say, it is not important to know information, just where it can be found.Googling “wiki collinear antenna” gets you https://en.m.wikipedia.org/wiki/Collinear_antenna_array In any case, the wikipedia explains it much better than I could.

0 Elkhunter521 Posted December 31, 2018 Author Report Share Posted December 31, 2018 Your teacher was a wise man (or woman). The best part is I almost understand it. Quote Link to comment Share on other sites More sharing options...
0 n4gix Posted January 1, 2019 Report Share Posted January 1, 2019 I had a teacher who used to say, it is not important to know information, just where it can be found.I had the same wisdom from one of my teachers six decades ago. I took it to heart wholly and it has served me well, especially when I was a work-study in the university library during my graduate days...

0 WRCD400 Posted February 17, 2019 Report Share Posted February 17, 2019 It is basically two or more dipole antennas mounted in parallel one above the other such as a Decibel Products antennas. You can see the loops mounted one above the other. Those loops are dipoles. The antenna below is a colinear antenna. Quote Link to comment Share on other sites More sharing options...
0 WRAF213 Posted February 17, 2019 Report Share Posted February 17, 2019 By stacking and properly phasing the antennas, you get higher horizontal gain and a narrower lobe in vertical gain (less multipath from ground reflection). Some collinear antennas like the one WRCD400 posted can have electrical downtilt, so just because it resembles a professionally built collinear does not mean it would be of utility for base station use (downtilt antennas cover limited areas close to a high-level site very well).
