### A 5/8 wavelength vertical for 10 meters. Post #224

How would you like to build a 10 meter vertical with some gain and a lower radiation angle than the usual quarterwave vertical? You can realize this goal by building and using a 5/8 wavelength vertical antenna on the popular 10 meter amateur radio band.

If you use 50-ohm coaxial cable as your feed line, you'll need a matching device at the base of the antenna to make the antenna work correctly. However, you can simplify the matching problem by using 450-ohm ladder line, a 4:1 balun, and a short piece of 50-ohm coaxial cable connected to the antenna terminal of your antenna transmatch. The 5/8 wavelength vertical also requires a ground radial system to realize its full potential. The radial system needn't be an extensive affair buried in the ground. I used six elevated 5/8 wavelength radials for my antenna. Thanks to the ladder line, the 5/8 wavelength vertical also is usable on 20 and 15 meters.
