Vanguard® Medium FTS 370d with TECK90

Flash Technology

Beginning with AC 70/7460-1L, the FAA liberalized regulations to permit the use of medium intensity lighting on broadcast and telecom towers up to 700’ AGL. Deploying a Vanguard® Medium FTS 370d system with TECK90 cable is more cost-effective and faster to install than conduit.

Designed for tall broadcast towers, the rugged TECK90 cable protects equipment from RF interference and damage. Impervious to all challenging environments including extremes of wet, damp and dry conditions, TECK90 cable resists chemical and mechanical abuse and is even suitable for hazardous locations.

Standard Features
