Alpha Delta
DX-Ultra

  Out of stock  

The Alpha Delta DX-ULTRA is specifically designed for high performance, full spectrum shortwave coverage plus medium wave (AM). The "Ultra" covers 500 kHz to 30 MHz. Absolutely remarkable low-noise, high-gain results are achieved as a result of the tapered wing design and ISO-RES inductors and parallel wire elements. The Delta-C Center insulator with built-in SEP Arc-Plug static protectors, provides protection for sensitive receiver components. This antenna must be center fed with a PL-259 type plug. The recommended center elevation is approximately 20 feet. The overall length is approximately 80 feet (25 meters). The Ultra is fully assembled - no cutting or soldering required. We recommend this antenna for receive only.

The user must provide the coax lead-in. If using a communications receiver, the coax lead in would have a PL259 connector at each end. Common pre-made lengths are listed in the table below. The top image is a graphic drawing. Mounting poles are not supplied. The bottom image is the actual antenna.
