Q176 Series Spiral Antenna

The Q176 Series are available in a standard 3-hole mount (model Q176-3) or pinned to a precision mounting-bracket (model Q176-2) for direct installation in a customer supplied Interferometer housing. The latter configuration provides improved unit-to-unit phase tracking for high accuracy interferometer applications.
