Compact 6dBi Collinear Antenna
This page details the construction of an easy-to-make collinear 360 degrees omni-directional, vertically polarised, antenna for 802.11b/g wireless networking. The antenna is very robust and compact, and has a gain of approximately 5-6dBi

Wire collinear for 2 meters
values indicated are calculated based on the excel program at 146 MHz design point adjust desired frequency for lowest swr
Collinear 5/8 wave omni 2 meters
The correlation between the dB and power ratio is dB = 10 log loutput power/input power A gain of 3 dB corresponds to a doubling of power
Antena Multibanda Colinear para HF
2-element 1/2 wave collinear J-Pole performed we fabricated two identical J-Poles using the dimensions in this document, and both of them performed quite well, with a resonant frequency toward the lower end of the 2-meter Amateur band and a VSWR of 1.5:1 or better over the entire band
