Package Bundle questions

Step-by-Step Antenna Tuning Guide:
1. Install the SWR Meter in Line
Turn off your radio. Locate the coaxial cable connecting your radio to the antenna.
Disconnect the coaxial cable from the back of the radio.
Connect the coaxial cable coming from the antenna to the antenna (ANT) port on the SWR meter.
Use a short length of coax to connect the transceiver (TX) port on the SWR meter to the radio's antenna jack.

2. Set the Meter to FWD (Forward)
Turn the SWR meter's switch to the FWD position.
Set your radio to the lowest possible power output (usually in AM or CW mode).
Select the frequency or channel where you intend to test your antenna's SWR (usually near the middle of the band).
Key the microphone (transmit without speaking) or use a CW key to transmit a steady signal.

3. Calibrate the SWR Meter
While holding down the transmit button (keyed up), adjust the calibration (CAL) knob on the SWR meter.
Turn the knob until the needle is aligned with the SET mark on the meter's scale (usually located near the far right side).
This step ensures the meter is correctly reading the forward power (transmitted signal).

4. Switch to REF (Reflect)
After calibrating the meter in FWD mode, release the transmit button and switch the meter to REF (Reflect).
Key the microphone again (transmit) to check the reflected power reading, which indicates how much of the transmitted power is being reflected back from the antenna.

5. Interpret the Results
Low SWR (around 1:1 to 1.5:1): Indicates a well-matched antenna system with minimal power reflected.
Moderate SWR (1.5:1 to 2:1): This is acceptable but may indicate some room for improvement in the antenna tuning or placement.
High SWR (above 2:1): Indicates significant reflected power, which could harm your transmitter. You may need to adjust your antenna or use a different one to bring the SWR down.

6. Adjust Antenna if Necessary
If your SWR reading is too high, adjust the antenna's length or position and re-test.
Repeat steps 2-5 after each adjustment to check if the SWR has improved.

7. Turn Off the SWR Meter
After taking the readings, turn off the radio and disconnect the SWR meter.
Reconnect the coaxial cable from the antenna directly to the radio.
Tips for Best Results
Test across multiple frequencies to ensure your antenna performs well across the whole band.

Always start with low power to avoid damage to your equipment. Keep your coaxial cables in good condition to avoid issues with the SWR readings caused by damaged cabling.
What is an SWR meter and why would I need one?

SWR (Standing Wave Ratio) meters measure the efficiency of your antenna system by comparing the power sent to the antenna and the power reflected back. A low SWR indicates that your antenna is well-tuned and is efficiently transmitting your signal, reducing the risk of damaging your CB radio.

How do I connect an SWR meter to my CB radio and antenna?
1. Connect the cable from your antenna system into the "ANT" connection on the back of the meter.
2. Take one end of a short jumper cable and connect it into the "TRANS" (the front is labeled "TX") connector on the meter.
3. Take the other end of the jumper cable and attach it to the CB radio's antenna jack
What if my SWR is high on all channels?
A high SWR across all channels indicates there's something wrong in your antenna setup. Here are some of the most common problems in getting your antenna tuned.

• Poor ground connection - Most mobile antennas need a good ground plane to work properly. Ensure your antenna mount has a solid electrical connection to the vehicle's chassis. Clean paint, rust, and dirt from the mounting surface. If your vehicle has non-metallic parts like RV's and sports carts or if the ground plane is inadequate, you can install ground straps to connect different metal parts of the vehicle, enhancing the overall ground plane.

• Bad coaxial cable or connectors - Inspect the cable and look for damage along the cable. If you see corrosion on the cable or connectors it's time for them to be replaced. • Improper installation - Check to make sure the antenna mount is attached and check your antenna stud to ensure the nylon washer is where it should be. If you have an antenna stud make sure your nylon washer is in the correct spot. For studs with a PL-259 the isolation washer should be just above the bracket.

• Obstructions - Nearby obstructions can affect your readings. Make sure you're in an open area and that the antenna is positioned so the signal won't be reflected off of the vehicle body or cab.

How do I know if my MXT500 has the updated software?
If you're serial number begins with 24 then you're in luck and already have the 8/24 updates. If not you can find the newest software and downloads here: Midland MXT500 Programming Firmware
What trucks does the CASP4 fit?

The CASP4 is compatible with Freightliner Cascadia P4 and P5 models (2018+)

Can I use this on the driver and passenger sides?

Yes. The adjustable design allows installation on either mirror.

ZZach★★★★★

So my Stryker I had received for Christmas is truly phenomenal, and just as I had hoped it performed flawlessly from the box. I had a few changes that needed made for antenna height, and location the best bracket. Within an hour of email each question I received timely responses with guidance/links where to find what I was looking for. A coworker and friend of mine recommended using this company for my radio needs, and they certainly did NOT disappoint. I will forever recommend them not only for their prices, their product, but also for the ease, assurance, timing, and excellent professional staff that have assisted me with any and all questions. My hats off to y'all, and I definitely hope one day I'm out your way to visit the shop and thank y'all in person! 5 stars isn't enough, but it's all I've been given as an option. Y'all deserve 50 stars!

I am a repeat customer for a reason! There are hundreds of places to buy radio equipment/accessories from but Walcott is my go-to because they are an honest and trustworthy site. Recent purchase was for a couple Stryker rigs with some bulk repair accessories and once again, the folks at Walcott came thru with another A++ transaction. Even with the custom tuning I requested, the units shipped on the 2nd day and arrived the next day in a well secured package and in fine shape. I have zero complaints and everything is working as it should. Will continue to use Walcott as a supplier of new equipment and especially for their fair priced, quality repair & upgrade components. These guys are way more than just another online CB retailer, much more!

All I can say is WOW, I remember venturing into this shop when they were a small but well recommended by fellow truck drivers on the road, many years ago. I am still impressed, they have grown into a great company and have many more things to offer. I ordered a GMRS antenna kit for my 24 Ram and the shipping time was quick. I will continue to be a customer, these folks are still at the top of their game in my book!!!

I ordered a President George cb radio on Monday, it arrived Wednesday. Well packaged, free shipping. Today (Thursday) I ordered a Stryker antenna, and got an email saying it had already shipped and will be delivered Saturday. Their response to orders is impressive! I was told that this cb/antenna combo is one of the best. I am impressed with this company so far, and I have read nothing but good reviews on them. I will definitely use Walcott Radio for anything I need down the road.

What a great experience! Could not believe how fast my radio was shipped. Ordered a President McKinley with the power mod and it works so much better than my stock McKinley. Dead key is about 3.5 lowest and pep about 25 highest with a good forward swing. My other McKinley stock would only put out 13watts pep with backward swing Hope this review helps someone else with their McKinley. What a great base and mobile radio!
