Thunderstorms, UpperAtmospheric Electrical Discharges and Wind Driven Sand/Snow Static Voltages Can Cause Equipment Damage.
However, Alpha Delta Has Many "Firsts" for Your Station Protection.

Alpha Delta Communications, Inc. has been producing industry leading RF management products for the communications industry for over 30 years. Our coax surge protectors, surge protected coax switches and severe weather rated multi-band and single band HF antennas are ALL made in the U.S.A. In our ISO-9001 certified production facility for highest quality and reliability. When you select Alpha Delta, you select quality!

Our products have been thoroughly tested and approved by Government, Industry and Military labs and agencies and have been issued NSN numbers by the Defense Logistics Agency (DLA), Cage TT3G50Code 389A5.

TT3G50 series coax surge protectors are the first and only designs to be tested and approved by the US Defense logistics agency (DLA) that have field removable caps ARC-PLUG gas tube modules, removable with the twist of a knurled knob! These protectors don't have to be cut out of the sealed coaxial cable circuit for module replacement. In other designs the entire unit has to be removed and discarded. This results in a major field maintenance advantage and money saving design. The designs do not use internal L/C components which, according to customer reports, can fail in the field we use precision microwave cavity designs. These units have NSN (National Stock Numbers) numbers assigned by the DLA. Cage Code 389A5.

The Alpha Delta design allows direct control voltage thru-put to head end equipment, instead of the "wire around" requirement of older designs.

The ARC-PLUG module and connectors are "O" ring sealed for all weather protection. Various connector styles and configurations are available.

Delta 4b•Delta-2B/and an Delta-4B/and coax antenna switches are the first and only surge protected coax switches to be awarded approvals from the Defense logistics agency for use in NATO and military applications worldwide. These units have NSN (National Stock Numbers) numbers assigned by the Defense Logistics Agency (DLA), Cage Code 389A5.

Models DELTA-2B and 4B surge protected coax switches and Model ASC-4B surge protected coax switches in a convenient desk top console are designed for low loss performance with excellent co-channel rejection through 1.3 ASCGHz,depending on connector model.

They are built with powder coated cases and are designed with micro-strip constant impedance cavity construction for best performance. They have a precision internal rotating mechanism with positive detent action for exact switch position indication. Check this site for various connector models.

The switches use a gas tube ARC-PLUG module which is accessible through the front panel for easy access if replacement is needed. 2 and 4 switch position models are available. Check WEB for details.

•Alpha Delta Model DX series HF wire antennas are unique in the industry, using severe weather rated components for extreme environments such as high tensile strength insulated solid copper 12 Ga. wire, and stainless steel hardware. Many models use internal gas tube static voltage protectors. The Model DX series has the most efficient performance we have tested----better than metal enclosed trap types or end-fed half wave models. The difference can be significant!
