To get the best performance out of your Stryker A-10 magnet mount antenna:
Antenna placement is critical on the vehicle
Pick a spot on the vehicle as close to the center as possible.
The roof is always a great choice;
This will give you the best radiating pattern and a decent ground plane.
Route the coax into the vehicle in a non-binding way so that the coax will not be pinched in a door, stepped on, or crushed.
Once you crush the coax, it can cause the shielding to contact the center core, which will need replacement at that time… So be careful with your routing options and take your time.
Tuning for Lowest SWR
Setting the SWR is a requirement of any new antenna and will give you the maximum performance of your Stryker A-10 Magnet mount antenna
Set your SWR in an open area with the doors closed on the vehicle, just as the vehicle will be when driving an open door or having the vehicle too close to a metal building will give improper swr when trying to set up your antenna
Tools for tuning your antenna
To set the SWR on your Stryker A-10 Magnet mount antenna, get yourself an external SWR meter, a pen, paper, a coax jumper, and something to trim the base of the whip. Run your jumper coax from the radio to the SWR meter input and the Stryker A-10 magnet mount coax into the antenna output of the SWR meter.
Loosen the hex screws with the supplied Allen key and let the stainless steel whip go all the way down inside the antenna base. Tighten the lower screw just enough to hold the stainless steel whip in place on your paper; make a few columns of 1, 20, and 40 across the top
power on and key up your radio and check the SWR on channel 1, then 20, then 40, there are videos and instructions all over the web on how to check your SWR keep adjusting the Stryker A-10 Magnet mount antenna whip until you get an acceptable SWR across the frequencies that you will be using.
Do you need to Trim the Whip?
Trimming of the whip may be needed when tuning the antenna, take no more than ¼ of an inch at a time off the BOTTOM of the whip and then re check the SWR. An SWR under 1.5 is ideal.
Once the SWR is set, tighten both hex screws on the antenna.
Maintaining Maximum Transmit & Receive
To keep the Stryker A-10 Magnet mount antenna in top performance, remove it from the roof every few weeks and clean off the base of the antenna and your vehicle roof, as dust, dirt, and water can get under the antenna. Also, check the coax connection at the base of the antenna and keep it clear and clean.
Wiping the stainless steel whip down is also a good idea to get the bug parts, tree sap, and whatever else got on it from driving around. These simple tips and essential maintenance will let your Stryker A-10 Magnet mount antenna last long and perform at its best.
