Wire collinear for 2 meters
Get water pipe, CPVC for hot/cold water at your building supply store, it is tannish white and 5/8 inch outside diameter.Cut to 6 inches long for all coils assemblies.Measure in on each end 2 1/4 inches and mark.Measure the spacing between these marks and make sure they are 1 1/2 inches apart.Drill a 1/8 inch hole through each mark all the way through the CPVC pipe

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
