Frequently Asked Questions
What is the difference between NMO-CAP and NMO-CAP-B?
NMO-CAP is the bright chrome option, supplied as TE Connectivity QWRC. NMO-CAP-B is the black chrome option, supplied as TE Connectivity QWRCB. Both use brass construction and share the listed dimensions and environmental specifications.
Will I receive both colors?
No. Each purchase includes one cap in the selected color. Order each option separately if you need both.
How do TE Connectivity QWRC and QWRCB relate to these SKUs?
Purchase Radios NMO-CAP is supplied using TE Connectivity QWRC, and NMO-CAP-B is supplied using TE Connectivity QWRCB. Select the Purchase Radios SKU that matches your desired finish.
Why is PCTEL MRC referenced?
This listing previously identified the chrome cap as PCTEL MRC. That name remains as a historical product reference for customers searching for a chrome NMO rain cap. This listing supplies TE Connectivity QWRC or QWRCB under the Purchase Radios ordering SKUs, not PCTEL MRC.
Will these caps fit every mobile antenna mount?
No. They are intended for compatible NMO mounts with the listed thread interface. Check the exact mount configuration and seating clearance; they are not universal covers for other connector types.
Does a cap make the mount waterproof?
The supplied QWRC and QWRCB caps have a listed IP66 rating when properly installed on a compatible mount. This is not an immersion rating. Correct fit and mount condition affect protection; follow the applicable installation instructions.
Can the cap replace the antenna during radio operation?
No. It is a protective cover, not an antenna or RF load. Do not treat it as a substitute for the antenna required by your radio installation.
Are the antenna mount and cable included?
No. This listing includes one selected rain cap only. The mount, antenna and cable are sold separately.
