A 9 dB 70cm Collinear Antenna From Coax
First remember that there is something called the velocity factor for coaxial cable. For RG58/U coax it is typically .66. All that aside now, lets calculate the 1/2 wavelength of RG58/U coaxial cable with a frequency of 444 Megahertz

Collinear Microstrip Patch Antenna
First, let's sharpen the meaning of the following three expressions in microstrip patch antenna MPA technology: radiator, patch, motif
Antenna collineare 144 MHz e 70 cm
Antenna collineare 144 MHz, ridimensionata sui 70 cm
Home-brew Compact 6dBi Collinear Antenna
collinear 360 degrees omni-directional, vertically polarised, antenna for 802.11b/g wireless networking
VHF 8db collinear
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 to compensate for the joints
