DIY Dipole antenna - Lightspeed - 31 July 2012
The attached diagram shows a basic dipole antenna, and how to attach it directly to RG58/u grade coaxial cable. (Cable grade is important)
The lengths indicated are for CB 27.500 Mhz Frequency. The quoted web site is a dipole length calculator that can be used to find the lengths of the dipole elements for any frequency you choose.
SWR adjustment is important. ( See Paul's description thread). Adjustment is by lengthening and shortening the lengths of the two dipole elements (orange and red arms). Start off by cutting each arm a little bit too long, this will allow for shortening. Shorten each arm by the same amount, as each should be exactly the same length.

Sorry mate, can't view the docx extension. Any chance of a pdf?
