Alpha Delta
ATT3G50 Series
Surge Protectors

The Alpha Delta ATT3G50 series of coax surge protectors offer wideband capability with extremely low loss. The innovative fast acting gas tube ARC-PLUG module can be replaced without tools. All models are weather proofed by the use of "O"-ring seals and all hardware is stainless steel. Made in America.

The ATT3G50 N version, shown above, can be used from DC to 3 GHz with typical dB loss of only 0.1 dB @ 1 GHz and 0.2 dB at 2 GHz. It can be used for receive or for transmit (up to 200 watts). Other specifications include:  impedance = 50 ohms, DC blocking = none, firing point = 350V less than 100 v/s, breakdown voltage = 20 to 30 V, surge current = 5000, size = 1 x 1.25 x 0.875 inches (25x32x22mm).

There are several versions of this device depending on frequency coverage, power capacity and connector type. Please note that all models can also be used for receive-only applications.
Please also see the optional UCGC ground clamp specifically designed for these devices.

Like all surge protectors we sell, these devices will not offer protection in the event of a direct lightning strike.

After hundreds of protective firings of the arc cartridge or after a catastrophic surge, the arc cartridge may fail and require replacement.
To test your cartridge use a VOM from center pin of either coax connector and to brass knob. Check resistance. 1 Mega ohm to infinity is good. Below 1 Mega ohm is "blown".
The ATT30G50 surge protectors are designed to allow quick and easy replacement without the use of tools.
Simply unscrew the failed cartridge and insert the replacement.
