Manuály a uživatelské příručky k anténě ALPHA

Alpha Antenna is a specialized manufacturer of antenna systems designed for Amateur Radio, Military, and Emergency Communications (EmComm). Owned by Productive Industries, LLC, and based in the United States, the brand offers a diverse range of High Frequency (HF), VHF, and UHF solutions, including Magnetic Loops (MagLoop), vertical whips, dipoles, and end-fed antennas.

Alpha Antenna products are engineered for versatility and durability, supporting both rapid field deployment and permanent base station installations. Their systems are frequently utilized for both DX (long-distance) and NVIS (Near Vertical Incidence Skywave) operations, providing reliable connectivity for users operating in challenging environments.

• Do I need an antenna tuner with the Alpha Antenna HF Base HD?

  An external antenna tuner is recommended if the antenna is installed over poor ground conditions or obstructed areas. If installed in a clear area with good ground conditions, a tuner may not be required.

• Is the Alpha Antenna V43 directional?

  The V43 is a semi-directional antenna. The signal launch direction is influenced by the placement of the grounded counterpoise wire.

• What is the difference between DX and NVIS configurations?

  DX (Long-Distance Communication) relies on low-angle radiation to reach distant locations via the ionosphere. NVIS (Near Vertical Incidence Skywave) uses high-angle radiation to cover short-to-medium distances, ideal for regional communications.

• What is the maximum power rating for the HF Base HD Antenna?

  The antenna is rated for 250W SSB, 125W CW, and 25W for Digital modes.
