Description
Which service are you actually operating on?
This has to be settled before anything else, because the listing does not settle it and the answer changes what is legal and what will work. The product title describes the Stryker SR-A10 as a 10 meter mirror mount antenna. The product description in the same listing describes it as a CB antenna. Those are two different radio services on two neighboring but distinct bands.
The 10 meter band sits around 28 to 29.7 MHz and is an amateur radio allocation, which in the United States requires an amateur license to transmit on. Citizens Band sits around 26.9 to 27.4 MHz, requires no license, and is limited by regulation to 4 watts on AM and 12 watts peak envelope power on single sideband. An antenna tuned for one will not be resonant on the other, and using a mismatched antenna raises standing wave ratio, which wastes power and can damage a transmitter.
So the first practical step is not measuring the mount. It is establishing which band this antenna is actually cut for, directly with Stryker or the seller, and confirming that you are licensed for whatever you intend to transmit on. Nothing else about the purchase matters until that is answered.
What the listing publishes, and the power figure that does not fit
The construction detail given is a 6 gauge solid copper conductor with silver plating and what Stryker describes as a high Q coil. Silver plating over copper is a real design choice, because radio frequency current travels along the surface of a conductor and silver is the most conductive metal available. Six gauge is heavy wire for a mobile whip. A high Q coil means a narrow, sharply tuned response, which gives efficiency at the design frequency and falls off quickly either side of it. That is a further reason the band question matters: a high Q antenna is less forgiving of being used off its design frequency than a broadband one.
The description is cut off mid sentence in the listing, ending after the words high Q coil and a stray digit, so whatever followed is missing.
One published figure needs stating plainly rather than repeated as a feature. A bullet claims a power handling capability of 10,000 watts. That number does not sit sensibly alongside either service named in the listing. Legal Citizens Band operation in the United States is capped at 4 watts AM and 12 watts single sideband, and even generous amateur limits are far below ten kilowatts for mobile use. Whatever the intended meaning, treat that figure as a marketing number rather than an operating instruction, and operate within the legal power limit for your service and license. Running an amplifier on Citizens Band is not lawful in the United States, and it is worth being explicit about that rather than leaving it implied.
The mount is the other half of the installation
Mirror mount means the antenna is designed to clamp to a truck mirror arm rather than to be drilled through a body panel or held by a magnet. That suits commercial vehicles and pickups with mirror stalks, and it avoids putting a hole in the roof. What a mirror mount does not automatically give you is a good ground. Most mobile antennas of this type need a conductive ground plane, and a mirror arm may or may not be well bonded to the vehicle body. A poor ground shows up as high standing wave ratio no matter how good the antenna is, and it is the most common cause of disappointing results after installation.
Whatever the band turns out to be, the antenna should be tuned with a standing wave ratio meter after installation rather than assumed correct out of the box. That is standard practice for any mobile antenna and it is the step that decides whether the installation works.
Living with it: what the specification fields say, and what they cannot mean
Several fields in the published record clearly belong to a different product and should not be read as describing this antenna. Two of the four feature bullets describe a paper white backlight for daytime use and floating waterproof construction rated to IPX8 and JIS8. An antenna has no backlight and no display, and floating waterproof ratings describe handheld equipment. That text belongs to a handheld radio listing. A specification field also reads Alcohol-Free, which is a beverage or cosmetic attribute, and another reads Wireless under display features, on a product with no display at all.
The listed product dimensions of 10.8 by 4.5 by 2 inches and the 1.08 pound weight describe the shipping package, which one bullet confirms by calling 1.08 pounds the package weight. The assembled length of the antenna is not published anywhere in this listing, which for an antenna is the single most consequential missing figure, since length determines both the resonant frequency and whether it clears a garage door. Get the assembled length from Stryker before ordering.
The color is given as white and silver, the product has been available since February 2016, is stated as not discontinued, and shows 716 ratings at an average of 4.6, which is a solid sample and a strong score.
When a different antenna is the right one
If the operating is from a fixed location rather than a vehicle, a base antenna at height will outperform any mobile whip. The Tram 1481 is a 17 foot amateur band base antenna and the Diamond X30A is a shorter alternative for a constrained mounting point.
If the operating is mobile but on the amateur two meter and seventy centimeter bands rather than the high frequency bands, the Comet CA-2x4SRNMO is the mobile whip for that, and the Tram 1180 is another mobile option. The rest sit under radio antennas. If what you actually want is broadcast television reception, that is a different product entirely and belongs in the TV antenna category.
Who should buy it and who should not
Buy it if you have confirmed which band it is cut for, you are licensed for that service if a license is required, and you have a mirror arm that can be properly bonded to the vehicle. Six gauge silver plated copper and a high Q coil are serious construction for a mobile whip, and the 4.6 average across 716 ratings suggests it performs for the people using it correctly.
Skip it if you cannot establish the band, because the listing describes it as both 10 meter and Citizens Band, and those are different services with different licensing. Before ordering, get the assembled length and the design frequency from Stryker, plan to tune with a standing wave ratio meter after installation, and disregard both the 10,000 watt figure and the bullets describing a backlight and waterproof floating construction, which belong to another product.
