Durham Radio Sales and Service Canada :: Amateur Radio :: Antenna Switches :: DELTA4B 4-Position Antenna Switch

DELTA4B 4-Position Antenna Switch 

Alpha Delta, Delta-4B, 4 position Coax Switch

Alpha Delta manufactures precision antenna switches employing the latest high-tech design. Cast aluminum constant impedance cavities permit the switching of two or four antennas while maintaining a constant 50 ohm impedance. These switches are rated at 1500 watts PEP. Silver-plated phosphor bronze micro strip construction ensures loss of less than 0.1 dB at 30 MHz with greater than 60 dB of isolation (0.5 dB loss and 50 dB isolation at 450 MHz).

The Delta switches offer three levels of surge protection! In the common position the common is disconnected from all antennas and all antennas are connected to ground. These switches feature a built-in surge protector. A replaceable D-4 Arc-Plug cartridge will divert harmful surges to ground. (Note: The Delta switches reduce the hazard of lightning induced surges. They will not prevent fire or damage caused by a direct strike). Made in the U.S.A.

Alpha Delta coax switches continue to evolve with significant manufacturing and design improvements! Introducing the Alpha Delta "B" series for models DELTA-2 and DELTA-4 coax switches.

  • New precision machined switch shaft and quadrant rotating mechanism for more accurate and stable switching performance.
  • Alpha Delta B Series Coax SwitchesHigher strength, lower resistance silver bearing solder.
  • Increased housing durability and abrasion resistance with powder coat finish.
  • New brass ARC-PLUG (tm) housing for improved gas tube positioning.
  • Same low loss micro-strip cavity design, positive detent switching, master antenna ground function, front panel removable ARC-PLUG (tm) surge protection module and excellent HF thru UHF performance as in previous DELTA switches.
  • Alpha Delta Communications, Inc. DELTA series coax switches are used worldwide in government, military and commercial applications and are manufactured in our ISO-9001 certified production facility in the U.S.A. We strive for excellence!
  • See label on back switch panel for "B" series identification and other important information concerning user cautions and Model D-4 ARC-PLUG (tm) replacement notes.
