Why ComAnt

In CompleTech's words (ComAnt catalog, March 2026):

"ComAnt® antennas are based on hermetically sealed IP67 grade water and dust proof construction where all electromechanics is moulded inside of closed cell PU-foam and covered by UV-protected fiberglass or ABS plastics."

"The antenna feed point is DC shorted providing basic antenna circuit overvoltage protection. Integrated RF choke prevents common mode currents and unwanted feedline radiation."

CompleTech names its typical users: "water management, electricity, oil and gas distribution to industry and military". Where ComAnt antennas work.

What changes on transmit is power handling and match; GNSS is receive-only.
