Alpha Delta DX-A

twin sloper antenna for 160 80 and 40 meters

Alpha Delta Twin Sloper antennas combine the DX effectiveness of the quarter wave with the wide bandwidth of the half wave dipole. The DX-A is designed to cover 160, 80 and 40 meters.

One arm is 20 meters long, while the other is 18.2 meters long. Sloper antennas are installed as an inverted V with ground return made through the metal mast or pole. These antennas use stainless steel hardware, copper wire, and efficient Alpha Delta "Iso-Res" RF coil coils.

Twin sloper antennas are designed for use on unbolted masts with metal guy wires, with a leading beam. The directive acts as a capacitive hat and helps tune the two slopers.

It is possible that introducing sloper antennas into a tower system that has other wire antennas connected may cause slight detuning of the other antennas. Some installations require the use of a tuner.
