HAM rig in place of CB

I'm studying up for the amateur tech radio license and understand that there are ways to make arig that works well for HAM on a jeep but can be tuned/powered down to CB when doing wheeling events. The HAM is important to me for my work in emergency management, but I also want CB ability for Jeep group stuff. I really want to only run a single antenna and unit. Is it possible? What antenna would be best if mounted above the spare? What unit has or could have the ability to tune down as to not obliterate the CB bands?

A legal ham radio with 10m won’t be able to Transmit on CB frequencies.

X2. Get a ham radio but have a CB radio too. This is how I mounted my Yeasu 2m and Uniden CB radios. My CB gets used 99 times for every time the 2m ham radio gets used.

2 radios

As Leadnut said, a legal ham radio can't transmit on cb frequencies.

My solution was a ham radio, icom 7000, installed in the jeep and a handheld cb for on the trail when needed. Some groups are moving away from cb and the range needed for cb on the trail is easily met with handheld.

Well, I do have a handheld CB so I guess that will do.

I thought that this would be the same in my case as well. I have a quick disconnect for my 11m in the back and a 2m to go in its place. Kinda of a waste for me as I have found I rarely use 11m any longer. I run APRS all the time and only one person in my group of friends runs 11m along with ham. I ended up with a front mount 2m/70cm dual band antenna in the front. I carry but only mount my rear 11m antenna when I am with a group that does not run ham. I guess it wasn't a total waste for me in the rare occasions I want to run both. My 11m is a Midland 75-822 and does not take up too much space in my center console.

Wow, APRS is where it's at! I'll get with our comm guy and see if that's something I could use.

Yes, APRS is fun to play and experiment with. I have a Kenwood TM-D710 and the A Band is always running APRS on low pwr. Fun to send emails and text messages to friends while out on the trail where I do not have a cell signal. So fun to play with stuff and even more fun when you figure out how to get it working! lol

I have the same Kenwood in mine. I haven't really explored everything APRS can do yet but I'm expanding a bit at a time.

I also keep a permanent mount CB in my Jeep for one reason. Even though Ham (and a few others like GMRS) are far superior radios in just about every way, not having a CB cuts you off from 90% of the people who run radios on 4x4 trails. In fact, most organized events require that you have a CB radio because that's what "everyone" uses.

Thanks for the photo. They really do look out of the way. Are they mounted to a luggage rack?

The Kenwood TM-D710 looks very compact - I like it! So that coupled with a 2m/70cm antenna mounted above the spare should work? That mount point was left by the PO - it ends right at the top of the tire so it is still a bit below the top roll bars, but quite a bit further to the rear. will that be high enough above plane?

Yeah, that Kenwood seems like a good one. What is your antenna setup?

You should be ok for 2m in that location but 70cm can be a struggle. Be sure to check SWR. You may need to move for 70cm if you can not get tuned properly.

Not only do legal HAM radios not include a CB band, but the antennae are different. The 2m HAM antenna can also be a 70cm. But neither would make an acceptable CB antenna. I'm likely to end up with both antennae on my Jeep, as I'll undoubtedly add a mobile HAM future. I currently have a handheld, but it's just not powerful enough.

I don't have any good pictures but it's mounted to my front fender with a flat mount that I installed with the included sheet metal screws. It sticks out between the fender and the hood on the driver's side.

I don't remember the brand or length of the antenna off the top of my head but it sticks up a little past the top of the Jeep. I do remember that when I was looking at antennas, it was a good quality one.

I attached a Ram ball mount to the top of the A-pillar to hold the display unit. It sits nicely up in the upper left corner of the windshield. Easy to see but not in the way.

Not sure if this is helpful but this is my mounting setup. I have a overhead console plate that runs from the windshield to the roll bar. The radio is mounted next to the roll bar and the operation panel above the mirror. Goal was to have the radio speaker where I can hear it, easy access to the mike/op panel and keep it up and out of any water that may enter during water crossings. This setup has work well for me.

They're mounted on a no-drill mount made by

Keep in mind too that as many cool things as some newer ham radios do, the majority of offroad communications still happens on the CB band. It's very rare I do a trail when CB is not the main means everyone uses to communicate with and chit chats on. Ham is great but have a CB too.
