Question:

I assume it would be reasonable to mount the outside unit on the Ladder at the rear of our 24’ class C

Hello Gary,

Great question. Mounting the SureCall OTR Antenna for Trucks, Semis, and RVs # SC55MR antenna on the ladder of your 24-foot Class C sounds like a good idea because it should check the key boxes for a solid installation. From the instructions *The antenna mounting location should: (a) allow the antenna to extend above the metal cab (b) be at least 6 inches away from any windows (c) provide at least a 12-inch radius clear of obstructions and other radiating elements, such as a radio antenna.

The built-in ground plane means it will work fine on your ladder, whether it’s metal or fiberglass, and the included mount should hold securely with a dab of the included LOCTITE. While the back of the RV can sometimes sit a little lower or be shadowed by the roofline, your ladder location should still provide good performance. If you ever need a bit more boost, a front-mounted mirror arm or roof-edge bracket could be a backup option.

What kind of Class C Motorhome do you have? Any fun adventures this summer?

So 1st thanks and I feel dumb I had done a bunch of work on a different RV with a ladder and now realizing I don’t have a ladder. We have the entegra Qwest 24R sprinter. So what is the best anntena mount for this rig? And do you have any pictures of the antenna on this model

@GaryR Sometimes I don't even know what I ate for breakfast, I would probably not realize it had a ladder either. Since your Qwest 24R doesn’t have a ladder, your best bets are the front passenger-side mirror arm or a roof-edge mount near the cab. The mirror arm is usually the top choice because it puts the antenna right up front, high enough to clear the cab roofline, and gives you the cleanest line of sight. A roof-edge bracket works well too if you’d rather keep it up top. Both spots check the important boxes for clearance, stability, and signal strength, so you’ll be set either way.
