Mounting a Yaesu FTM-350 in a 2013 Ford Fusion

I’ve been intending to document this installation for over a year… but hey, procrastination!

A bit of background to start. I needed a way to permanently mount my Yaesu FTM-350 in my 2013 Ford Fusion without damaging the interior. Requirements were for something that could be positioned unobtrusively, but made the radio easy to see and adjust from the driver’s seat. It also needed to be easily reversible should I need to do so. I also wanted something that would allow me to quickly detach the control head from the mount should I want to stow it out of view. I looked at windshield and dash mounts, cup holder mounts, and seat post mounts.

This write-up will document only the radio mounting process. Power and coaxial cable runs are pretty well-covered in other online and print resources. Following is what worked for me in my application. It may or may not be applicable to your installation, but may give you some ideas. As always, your mileage may vary, and every situation is different. As such, I cannot be responsible for the outcome of your installation.

First, the radio. The Yaesu FTM-350 has a remote head that does not directly mount to the main radio. There is a single mounting point on the back of the head – a metric 5mm x 0.80 threaded insert. It matches up with a suction cup mount supplied by Yaesu, but it’s an odd thread compared to most every aftermarket mount I could find. I did eventually find a couple of mounting or adapter options, but most required you to buy the entire proprietary system they mated with. This was not the direction I wanted to go.

I found the main body of the radio could be nicely mounted underneath the passenger’s seat with separation and power cables well-protected inside some spiral-wrap wire loom. This meant I was looking primarily at mounting locations in or around the center console. I had considered fabricating a bracket to hold the control head in place just ahead of the shifter in a storage space that is part of the console, but that would eliminate that storage area and likely meant the head would not be easily or quickly detached if needed.

I don’t recall when or who pointed me to ProClip’s two-part mounting system, but I’m pretty sure it was my friend Clint, KC0JUO. Regardless, it’s a pretty darn slick system that consists of a vehicle-specific mount (there are also different mounts for different mounting locations in the vehicle) with device-specific holders that then attach to the vehicle-specific mount. The result is essentially a custom mounting solution that’s unique to your configuration. I used their products as the basis of my installation, with a few modifications. I don’t receive any benefit from ProClip for recommending their products, but really like them!

I started with the ProClip angled console mount for the 2013 Fusion. It features a flat surface with an industry-standard AMPS screw pattern. Here is a picture of it installed in my vehicle.

Since the mount features the AMPS pattern, there are a number of options available. After looking at my situation, I decided I wanted the ability to move the radio around a bit if needed, so I selected a swivel mount. Specifically, I selected a ProClip AMPS to Richter swivel mount. More on the Richter mount shortly. I also purchased a 3/4″ thick ProClip AMPS-pattern spacer block to allow me to move the radio head out from the console a bit, but in the end, I didn’t use it. Here is a photo of the swivel mount installed on top of the console mount.

Back to the Richter mount. Because the FTM-350 has just a single mounting point on the back of the head with the unusual thread pitch, I needed something that would easily adapt from that metric 5mm x 0.80 thread to something I could integrate into the rest of the system. I looked at ball and other mounts, but everything was too bulky. Enter ProClip’s Richter female mounting plate. This plate is super thin (less than 1/4″ thick) and includes an adhesive pad that can be used to affix it to the back of your device. I opted to drill a single small hole in the center to allow use of a stainless-steel button socket cap screw to mount it more securely without interfering with the mount itself. Were I to do this again, I would skip the adhesive since I find it tends to “bind” on the fingers of the Richter mount and make separation a bit more challenging at times. Following are pictures of the adapter plate after drilling the hole, and with the cap screw installed.

Once the Richter adapter plate is attached, you simply mate the plate with the corresponding part of the swivel mount and slide to lock it in position. Since the control head only has a single cable running back to the main radio, detaching is as simple as disconnecting the modular connector, then sliding the Richter mount apart. The microphone stays attached to the control head.

Here is a photo of the finished installation. I met all of my initial criteria and have a radio installation that looks professional and doesn’t interfere with operation of the vehicle or get in the way of any passenger. This installation position does cover the passenger-side climate adjustment controls, but those are accessible from the vehicle’s touch panel above the console, so nothing critical is obscured. I hope this gives you some ideas for your own installations!

April 1 – “Tape Measure” Yagi Antenna Workshop

If you have been interested in participating in a fox hunt but you don’t have a directional antenna, we have the perfect opportunity for you!

Clint Miller KCØJUO and Paul Cowley KB7VML with the Story County Amateur Radio Club are hosting a 2-meter “Tape Measure” Yagi Building Workshop. We will be supplying a complete kit and hands-on instruction for you to build your own WB2HOL-design tape measure antenna, with some slight enhancements to the design.

These antennas have a really great front-to-back ratio with a very deep notch in the pattern toward the rear. It uses three steel “tape measure” elements that fold easily to allow you to quickly get in and out of your vehicle and yet remain stiff enough to be self-supporting when hunting for a hidden transmitter. Between hunts, the elements can be folded or rolled to reduce storage space. This antenna design has been in use for decades for ARDF and transmitter or fox hunting, but also can be used to contact astronauts on the International Space Station, make satellite repeater contacts, extend your HT range to hit that repeater in the next county, sniff out local RFI noise, locate a stuck transmitter or jammer… the options are endless.

There are no special skills or tools needed to participate in the workshop, just the ability to follow instructions and an interest to have a good time. Each participant will get a complete kit with all the parts needed to build an antenna with a male BNC connector on the end of the coax. Adapters for your HT or handheld scanner will be available for a small additional fee when registering. We will have all the tools and supplies available so you will leave the workshop with a tested and functioning antenna. During the workshop, we will provide some additional ideas for enhancements to make later if you so choose. If you bring your HT or handheld scanner, there will be a fox hidden outside for you to practice finding.

 

 

If you are not able to attend but are interested in an unassembled kit (with instructions) and can make arrangements to pick it up in Ames or Urbandale, please register and put in the comments that you are only ordering a kit and will not be attending on 4/1.

Preregistration and prepayment is required so we can order enough supplies and save on shipping costs.

Due to additional interest, we are extending the pre-registration deadline to 8:00am on March 29th… but with an increased cost of $20 per kit (because of increased component and shipping costs).

CLICK HERE TO REGISTER

Payment is due at time of registration (includes ALL materials necessary to complete one antenna)
Questions: Contact Clint Miller KCØJUO at isuforester@hotmail.com

We look forward to seeing you at the workshop.

Welcome to my website… it’s been a long time coming. My last site was last updated in 2001, nearly 15 year ago! I purchased the kb7vml.net domain a while back and am finally up and hosting my own WordPress site. I hope to document and share my experiences and knowledge gained for the benefit of others.
