HORWIN AD-4508 is a broadband 8-element VHF antenna with a dipole element of the “loop vibrator” type. All structural elements are short-circuited by direct current. The design of the antenna allows you to form a straightness diagram by changing the installation station of the dipole elements from the metal cannon (pipe tube) on which the antenna is installed. The mast (pipe stand) is not included in the antenna set.
