Tulsat
tulsat.com TULSAT leading US distributor and repair center for cable TV (CATV) equipment — headend gear, fiber nodes, amplifiers, taps, power supplies — founded 1985 by brothers David and Ken Chymiak in Broken Arrow, OK (100,000+ sq ft). From a bankruptcy buyout it became exclusive Master Distributor and authorized service center for Scientific-Atlanta (now Cisco), plus Motorola/Arris, CommScope, ATX, Quintech. It merged into public ADDvantage Technologies (NASDAQ: AEY) in 1999 (peak revenue $50.3M in 2005), then the cable segment was bought back by David Chymiak's Leveling 8 Inc. for $10.3M in 2019 — private again. Today: ~25 staff, est. ~$10M revenue; group includes NCS Industries (PA), ComTech Services (MO), Tulsat-Atlanta (GA), Nave Communications (MD), Triton Datacom (FL). Core value: largest legacy/obsolete CATV parts inventory + factory-authorized repair, a lifeline for aging networks as cord-cutting shrinks the industry.
