VHF 8db collinear
I started to build the antenna by cutting four lengths of wire, the measurement is 38.75ins for a half wave @ 145mhz but I cut them at 39.75ins
VHF Collinear-Dipole
VHF Collinear antenna project with matching-system for 2 dipoles model Gain = 5.15 DBi
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
Coaxial Collinear Antenna
Another components are a connector type F or SMA, insulating tape, PVC pipe with the outer diameter 12 mm and suitable end-seal for this pipe
