The Laird (TE Connectivity) LA350GT is a user-replaceable gas discharge tube designed for Laird’s Trapper series of in-line and bulkhead-mount lightning arrestors, covering the LAIL350NN, LABH350NN, and LABH2400N models. Rated for 0-1000MHz operation and a maximum power handling of 1000W, the gas tube provides surge protection by ionising and safely diverting high-energy transients such as lightning strikes to ground, protecting connected radio and communications equipment downstream. As gas discharge tubes degrade with each surge event they absorb, keeping a replacement LA350GT on hand lets you restore your Trapper arrestor’s protection quickly after a lightning event without needing to replace the entire unit. A practical stock item for any site running Laird in-line or bulkhead coaxial lightning protection on towers, base stations, or outdoor communications equipment.
