Here is a link to a Dipole Calculator
The dipole is for 11m band or CB 27mhz band tuned in the middle of CB band, so around 27.200Mhz
Good performance on 27.555Mhz as well with current setup
It uses T section with 1:1 balun with embeeded so 239 connector and high quality insulators on each ends.
Antenna can be used on permanent mount or portable as being light weighted and compact in vertical or horizontal position or tilted towards earth as sloping dipole
