Our point is that we don't have one...
A standard F-port, with a simple 2, 3, or even 4-point contact, provides a point contact of only a few thousandths of an inch per side. Such a small contact area is inadequate for reliable, corrosion-free connections. The CamPort, however, does not have individual points of contact, but provides a full surface contact between the cam and the center conductor.
Antronix thrives under pressure...
The potential problems inherent in the minimal contact area of a standard F-Port are compounded by the fact that the conventional point contact offers little or no control over contact pressure. The insertion of center conductors into the port has a tendency to change and reduce both the contact pressure and the contact resistance. This degradation of the contact with the conductor in a standard F-port is the unavoidable result of the eventual weakening of the spring tension of the contact material. The advance design of the auto-seizing mechanism of the CamPort, however, enables the contact to remain strong even after constant use and re-use. This unique feature allows the CamPort to remain "open" when not in use. Only after the conductor is in place does the auto seizing mechanism tighten to the proper contact pressure. Since there is no friction when the center conductor is removed or inserted, the contact pressure remains constant each time the port is used.
Always a full plate...
The plating on a standard F-port contact continually wears away each time the drop, trap, or terminator is put on the F-port. As the plating wears down, corrosion builds up. This corrosion build up will continually weaken the signal until the entire signal is eventually lost. The obvious result of corrosion damage is an increased number of service calls. The plating on the CamPort's auto-seizing F-port however, is not prone to such wear and remains full and intact for a longer life requiring fewer service calls.
