High Definition BNC Connectors

____________________________

The Shadow ™ in the trade name for the best high definition BNC connector available at any price Shadow™

BNC connectors fit all standard broadcast cables and utilize most standard existing tooling. These connectors are
made from precision machined brass. Insulator material is high density TFE to maintain a perfect dielectric
constant. Bomar connectors utilize a .042 diameter gold plated contact pin to maintain the best return loss in high
definition applications.

The Shadow™ is precision machined (not die­cast) from brass. A special black nickel plating is
applied for a beautiful finish that is easily
identifiable as a high definition connector. Each
connector is precision matched to a specific cable
type.
Uses standard commercial tooling. However,
Bomar die sets are available for use with
KTH1000 frame.
