F-Type Right-Angle Adapter, 75 Ohm Line
The right-angle orientation changes the cable exit direction by 90 degrees — useful when a straight adapter would force a bend radius that kinks the coax or when the connector sits against a wall. The adapter is rated to 2 GHz, covering the full F-type band for satellite IF, DOCSIS 3.1 cable modems, and legacy CCTV video distribution.
75 Ohm Impedance and 2 GHz Bandwidth
If your system is 75 Ohm throughout (cable, splitter, terminator), this adapter keeps the line impedance continuous. The 2 GHz max frequency covers the full F-type application range; beyond 2 GHz the POM dielectric and the threaded interface introduce mismatch loss.
Body and Contact Construction
The centre contacts are brass and phosphor bronze, tin-plated. Tin plating is adequate for the low mating-cycle count typical of an F-type adapter (install once, leave it); for frequent reconnects a gold-plated centre contact would be preferred, but that is not what this part carries.
Right-Angle vs. Straight — 222157 Comparison
Both are 75 Ohm, 2 GHz, nickel-plated brass, and tin-plated centre contacts. The difference is the body angle: the 222F-90 exits the cable at a right angle; the 222157 exits straight. Choose the 222F-90 when the cable run needs a 90-degree turn at the adapter — for example, routing coax flat against a wall plate or inside a shallow enclosure. Choose the 222157 when the cable continues in line with the connector.
