Two-Way Radio Antenna Mount

I was reluctant to drill a hole in the roof for my ham radio antenna, not because of the hole itself, but because of the height of the antenna. So, I looked at mounting the antenna to the fender.

This proved to be a challenge due to the design of the hood and fender. A simple "L" style bracket would require some modification.

I fabricated a 1/16" piece of stainless steel and mounted it to the upper left fender, opposite the radio antenna. The black rubbery trim piece is easily removed and two holes with stainless sheet metal screws secure the bracket to the fender. The fender metal there consists of two pieces with weld spots, so it is plenty sturdy for most any type of antenna.

The next task was how to route the antenna cable. I looked for a convenient path to come through the firewall, but that would have required drilling a hole. Then, I noticed a rubber plug near the door hinge. From the stainless bracket, I routed the antenna cable past the bladder bags stuffed into the upper fender pocket and came under the door hinge to the plug.

Shazam ... using a piece of #14 electrical wire, I easily fished the antenna cable through to the area above the driver's feet and from there to the radio.

The final challenge was to get power from the battery compartment located beneath the (power) driver's seat. What a pain. I wonder why the engineers thought it best to locate the battery there?

The antenna is now secure and can easily be removed at trade in time ... "like it never even happened" !

Glad it's done!

My 2 mtr will be handheld only for the time being....

I fear ruining the warranty so I'm going to mount my HF antenna on the trailer hitch/receiver. I won't be working HF while driving so it'll be a temporary mount. The station will be by the slider so I will have an option of setting the antenna outside the side door on my camera tripod instead, like for a quickie or in case of bad weather and needing a quick dismantle.

I'm seriously considering adding a golf cart battery just for the ham station, under the table at the slider door... even though I have two agms and the heavy duty alternator coming... any thoughts on that are welcomed.

Ham here also- my only comment would be watch for RF interference to the vehicle> Ford is very specific about where antennas can be mounted and how much power at what frequency is to be used..

I've had some weird ones over the years- Had a 75 (IIRC) VW Rabbit that would flash the blinkers at double rate with 25W on 2m and with 50W the engine would just shut down.
Had a late 70-s Buick company car that the cruise control would drop out with more than 10W on 2M....

I checked it from 5 to 50 watts this afternoon and didn't see any smoke. I'm on 6 meters, 2 meters, and 440.

I had a metal fabrication shop cut and bend the stainless from the template that I made.

I would be happy to send you a template. You can cut and bend yourself, or take it to a local metal fabrication shop.

I run 27 Mhz, 43 and 48 MHz, 150-160 Mhz, 450-470 Mhz and 2.4Ghz. Only problem has been a dash cam that causes the tire pressure monitor system to display when there is no tire problems. I also get the TPMS light at certain locations near congested RF sites. I am a communications technician working business band and public safety frequencies. I have an antenna farm on the MR T150 with various RF power outputs and no vehicle electrical or interference problems other than the TPMS.

Hi spongebob,
Would appreciate it if you could send me the template as well.

I picked up my 2017 148" Mid roof last month and have been debating whether or not to use my Diamond K400 lip mount. I'm hesitant though after looking at the deflection that the stock radio antenna suffers at highway speeds, especially with cross winds which have been bad this year.

Curious what rig are you running?
My Icom IC-7100 has been itching for her new home. Still don't know what I'm going to do about the HF but really like your solution for the upper bands.

Hey There,
I'm Cale, K4CDN, and it looks like I am trading my '14 E350 for a slightly used '15 Transit. Would you mind sharing your template with me? I have a local shop who recently created a mast mount for a new repeater install and I'm sure he could handle this request. Thank you for your post, I was wondering where I was going to start re-installing my Kenwood!
