On the road with "Cactus" and Miss Joan

My F-150 Installation

Posted in Uncategorized by k4ymb on June 30, 2014

Dear Folks,

This is an email that my friend Ken, NJ4C, sent to Paul, K4BET, about his installlation …. This might be some help to others… "Cactus"


Cactus alerted me to your F-150 installation problems and since
today is a rainy day and I can’t work on the farm I thought I’d
take pictures and describe my installation in hopes it might
help you. I am able to work all bands on my radio and have
worked lots of DX and alternator noise is of no consequence.
I also needed to document my installation to help another
ham with his installation.

When installing mobile installations there are different problems that
occur that we don’t have at our shacks and I know you know that.

My installation has never given me a moment’s problem since I figured
out that it was really OK! To start with, I have a car installation and an
2012 F-150 installation. I will go over the F-150 installation. My radios
are Kenwood 480HX radios that Kenwood recommends the two power leads
be connected direct to the battery. My antenna is the Tarheel 200-HP.
The radios are 200 watt radios. Both my radios use the Turbo Tuners
and after about 3 years with my car and 2 years with my truck…
….I have had no problems at all. All power wiring on both installations is run
to the motor area through the channeling underneath each of the doors.
On my F-150, I have attached the Tarheel mount to my Camper Hitch.
In both my installations is the success I had hoped for. There are no
special or magic tricks involved in either installation. So, lets begin:

1. Installed 2 ground straps to antenna. One small ground strap is
attached to the antenna mount and runs alongside the coax back
under the truck to the frame. One large ground strap is attached
to the hitch mount which is welded to my Camper Hitch.

2. Radio Grounded to Frame. My radio is under the back seat and a small
ground wire (yellow connector) is run directly to the frame underneath
the cab. You can see the Turbo Tuner next to the radio. The
radio is operated with the control head that I have placed next to
the driver’s seat.

3. Negative Battery Connect. I run the negative wire from the radio
direct to the battery stopping short to add fuses and chokes with
the wire running through a small choke or two.

4. Positive Fuse Box Connect. I run both positive (10 gauge)
power wires direct to the fuse box area stopping short to roll
each wire around each large choke and to add fuses.
Also, for added measure you can see the two wires running
through two small chokes where I connected the wires to
the fuse block connection.

5. Use of Chokes at Antenna. At the antenna I have used plenty
of chokes on the antenna power wire and I have also run my coax
through and around another choke. Chokes and grounds are good
and help hold down interference.

I hope this might help you in someway..I often think that my use
of Kenwood radios (since 1982) have made mobile operations
trouble free.
