PD458 Series
Storm Chief™ Rugged Broadband Omni

The PD458 is designed for use in areas where electrical storms are highly prevalent. An exposed lightning spike at the top of the antenna is directly connected to the support pipe by means of a 7/8 in. (22 mm) O.D. high conductivity copper conductor. In laboratory conditions, the PD458 has been directly subjected to 190 kiloamps without effect on performance. The radiating system of this antenna consists of six 1/2 wave elements mounted coaxially. The copper 7/8 in. (22 mm) diameter feed-line shunt feeds each center grounded element. For a power rating of up to 1000 Watts this antenna can be modified with a fitting which will accept 7/8 in. (22 mm) diameter 50 Ohm cable directly. Specify PD458K for the high power version. A reflector assembly is available. Specify PD10000-2 for the 450-470 MHz models.
