1985 4Runner CB Install...

I find myself on logging roads here in Oregon on my way to my gold placer mines. There are many log trucks at times and so I needed a CB to communicate. With a CB you can keep in touch with trucks coming down the road, or up, and know when to haul ass and when to pull over.

I bought a Uniden 510 XL Pro, a 4 foot Firestik adjustable tip antenna, an SS-204 door edge swivel mount w/K4 Stud, an SS-3M medium duty spring, and the terminal end wire 18 foot to use with K4 stud. All for about $100.00.

Basically as pictured I set the mount between the rear door on drivers side ( 4screws). I wired the terminal ends to the cable and attached the ground ( See pic) and notched out the upper rear tail light to run the coax through. Inside the rear light space I made a small slit in the rubber seal that is used for the rear tail light wires then sealed it back up with liquid rubber.

I ran the wire in the body area where jack is up to the back seat behind the panels, then at 90 degree's turned the wire to lay under the rear seat ( covered with soft rubber padding then duct taped down neatly) into the other side of panel on passenger side. From there I worked the wire under the passenger door trim then back across under the floor cover to back of radio. It was exactly 18 foot -YEA! :bravo:

My truck had a quartz clock there under the stock radio. I removed that and used the power and ground wire that went to the clock and wired to CB. I had to shave a bit off the clock mount but got it centered and fit to perfection. ( See pics) I used an existing screw mount to put one screw in to hold the transmission microphone down tightly drilling no holes into panel there.

When I set up a SWR meter initially at the height in the picture with spring attached ( adding height) my channel 1 read 1.4 and my channel 40 measured .08. I removed the rubber tip off the end of the cable and turned the adjustable screw 1 turn at a time and tested. At about 2 and 3/4 turns my measurements were a perfect 1:1 both on channel 1 and channel 40. I replaced rubber tip.

I then called a friend who lives about three miles away from my house and we could communicate perfectly. This is in the city too with many hills, transmission wires, and houses between.

All in all Happy Happy Happy :lmao:

If you do a CB take note on height of my antenna mount on back tail gate measuring up 4 feet plus spring. At that total height you could place the antenna anywhere on truck and get similar results. 1:1 is as good as it gets and utilizing the full 4 watts :shrug:

Nice job on the install! I've done a lot of radio installs, and that antenna mount is by far the best one to use. I absolutely hate it when friends buy the one that allows coax to be screwed into the mount, they never last very long, get corroded easily (unless you put outdoor tape or antenna seal on them) and I find the coax usually breaks from the PL259 connector after about a year or two. Its also a spot that gets broken from all sorts of things, like branches hooking the coax and ripping it out of the connector!

I've got two antennas on my truck, one for 2M/440mhz and one for HF, and I run an Icom radio:

Works very well for me!

I was thinking to upgrade my radio eventually. For now I will only use it for the logging roads.

Later when I move to my property deeper in the mountains I will go with what you have I am thinking. I do not have a lot of experience so need to read up on things...Even so it was fun to participate in some skipping the night before last. I was talking with someone in the Mohave Desert...

Wait till ya get that really long skip to somewhere like Australia! When that bug bites ya, look out! You'll be spendin' money on radios and antennas! And if you branch out to the ham radio side, it multiplies by at least a hundred!!!! LOL!!!!
