Are you someone who loves to go portable with your amateur radio equipment? If so, you know that having a reliable antenna system is crucial to communicate with other ham radio operators. 

The Elecraft AX1 antenna system is a popular choice when it comes to portability. One way to set up the AX1 which may get better results is to use a window mount with your antenna. 

In this article, we will explain why a homemade car window mount for the Elecraft AX1 antenna system might be a good choice and how to mount the Elecraft AX1 Antenna System on a car window.

Benefits of the AX1 Window Mount:

One benefit of a homemade car window mount is improving both receive and transmit signals. The Elecraft AX1 is an omnidirectional antenna which will send and receive signals from all directions. One way to help maximize signals from and to the antenna is by mounting the AX1 outside the car window. Using a few techniques you can maximize signals to and from the Elecraft AX1 Antenna System. 

A homemade car window mount allows you to position the AX1 in a way that will reduce interference from nearby objects and eliminate your body capacitance. A window mount will also improve outgoing signals as most of the antenna will be above the roofline of the car.

Another advantage is that it is easy to install. You can create your own mount using simple materials like a double BNC connector and about 12 inches of 4 inch wide bar stock. This means you can easily install and remove the mount as needed, allowing you to take your mount wherever you go.

Lastly, properly designing your own sturdy homemade car window mount will ensure that the mount is properly attached and will reducing the risk of antenna damage.

 KE2YK’s Notes:

As an Elecraft AX1 user let me just say that the window mount accessory is another QRP treat! I’m here to offer you some tips for maximizing the performance of the Elecraft AX1 Antenna System on a car window mount.

First things first, take your time to securely fasten the mount to your car window before attaching the antenna. I cannot stress this enough. A wobbly or unstable mount can not only affect the performance of your antenna but may damage your vehicle. So, double-check everything before you start calling CQ.

Once your mount is in place, remember to optimize the counterpoise for the band you are going to operate. The KX line of transceivers have awesome ATU’s but getting the SWR in the ballpark is important when working QRP. Don’t be afraid to experiment with different mounting locations on your vehicle until you find the sweet spot that works best for you. As always, the key to optimal performance lies in fine-tuning.

So, my friend, with these tips in mind, you’re all set to explore the benefits of using a car window mount with the Elecraft AX1 Antenna System. Trust me; it’s a world of its own up there in the airwaves, and you’re in for another QRP adventure!
