Hi all,
I have a Uniden Grant CB and a wilson 1000 laying around I have had for years, so I figured I would install it in the EX.
Other than throwing a magnet mount on the antenna and throwing it on the roof I thought I would ask where are some of yours? and how did you mount them? Anyone use a standard lip mount somewhere on an EX before if so where? Any other suggestions on the setup would be welcome as well.
Thanks
Robb

I am using a mag mount until my through-the-roof NMO mount from Diamond. Any "lip" mount won't give you a decent ground plane - it will work as expected in one direction and will suck in the opposite direction. I advise anyone to avoid lip mounts unless you have a lease. If you own it do it right - through-the-roof mounts are easy and reliable, and can be easy plugged if you trade it in or sell it.
That is really clean looking, I really like that idea.
Did you fab that peice of sheetmetal to reduce flex under the hole?
How is your reception on the CB?
Thanks - I would have never thought of that location!!!

I hear what you are saying, but a 2 meter 5/8's wave on top of an already tall Ex is a little prohibitive, don't you think? A quarter wave might be a different story. I have my Larsen NMO 150 on a stainless angle lip mount in the same location Stewart shows and it works fine. I can work all the repeaters in my area with no complaints of audio quality. Is it ideal? no, is it a good comprimise? I have to say yes.
Sorry to hijack the OP, guys, I know you were alking about CB antenna's and we kicked it over to Ham antenna's. But its still the same problem right? A practical place to mount your antenna.
I also now have a scanner ant about 2ft in front of that.
Granted it gives me a total height of about 13ft now, but the only times it has been an issue is a fully enclosed drive thru(bank or whatever) worst case, hop up and unscrew it.
Hi Stewart. It's a Wilson Silverload, but basically the same thing as a FireStick. I've got a 4' whip on there now that works better in this location. I could tune the 2'er over a narrow band, then SWR's would go through the roof on channels further away.

Not prohibitive when you get it as a fold over...
Even tuned, those ones mounted at the driver side pillar will only get decent distance foreword and right of the truck...rear and left reception/transmission will suck - is all about the ground plane. With CB already underpowered, why cut the transmission distance even more when they can do it right for probably the same amount as all that custom work they are doing? Doesn't make sense to do all that work and still have issues.
Widely considered the best source for mobile antenna placement is <http://www.k0bg.com/>. But it probably goes into far more detail than what you are interested in. Short answer is that center of the roof "full" size (1/4 wave) is the best. Anything else is a compromise. But a compromise is better than nothing. At least you are on the air.
A short base loaded antenna on the roof is probably about as efficient as a much larger antenna mounted on the hood. I would guess that they are similar in operation.
RF bonding of the body parts and the radio is usually as important as the antenna placement.
I have a thru window mount on the back driver's side wing window and it pretty much sucks. I have a Yakima rack with bikes, a kayak, etc. so my assumption has been a roof mount wouldn't work? Anybody have advice on how I might make this work? Thx, gm.
I have duals mounted off of the side view mirrors. Looks clean and cool. Got the splitter and brackets from Radio Shack. I have the cord running through the mounting holes on the mirrors.

For modern cars the through window connections are a scam. Most (all?) glass has a metallic film to block UV. Some of the signal will bridge the gap but it is highly attenuated.
I would go with the hood mounts mentioned above. You could put roof mount near the edge but the inconvenience factor IMO would more than offset the slight amount of lower loss.
