Roof Mount Antennas

Hummer Tech

Aug. 01, 2002 By Allan M

When you've got a fully-outfitted rig that includes all the latests gadgets such as a GPS unit, CB radio and, among other things, a cell phone, you end up with a lot of wires and a few antennas to have to deal with.

As is the case with my Hummer, there are a lot of antennas to deal with and the trouble is where and how to mount them. You want it looking like it belongs there, not like a gypsy installed it.

Well, here's how we went about installing our various instruments.

Both GPS & 800 Mhz Antennas after being painted to match color of truck.

  GPS Antenna by Garmin (marine model from West Marine @ 800-538-0775)   

800 Mhz - LoPro Antennas from Northpoint Comm. Products (312-944-4447). They also make them for UHF (460), & the cellular band.

Due to the location I picked, I had to remove the roof lining. This is was also a good time to add sound & heat insulation to the roof. Here you can see just the drivers side is covered at this time.   

Also, note the location of the two ribs, they are great for mounting equipment too. 

  Now, I wanted a single antenna can be mounted in the center, just behind the bar above the front seats. Only one cover on that cross piece needs to be removed for installation and would be a lot easier then my job. ( I will add a photo later showing you where I am talking about.)

Here is the completed installation of the GPS, CB, & 800 Mhz antenna (like cellular).   

The GPS required 3 holes for the screws, & 1 for the cable.   

CB - A K-40 antenna required a 7/8 hole.   

800 Mhz - Low-Pro required a single 3/8 hole and uses an adhessive pad to bond to the roof. Easy to install and works very well.
