Radio/CB Antenna Replacement
We have the long steel mast Radio and CB antennas on the roof of the Anthem. They seem to hit just about everything. Has anyone replaced them with a shorter or rubber mast? The radio antenna does have an adjuster to lay it down, but of course its installed left/right, not front/back. Just looking for other ideas then these antennas. hitting tree limbs and some bridge overhangs, I'm not sure these whips will last...
Thanks!

Under the RV Lifestyles forum the is Hobbies, Passions, and Passtimes section. In that forum there is CB & Ham Radio.
There are real pros that can help you out there.

Longer antennas... Longer range
Shorter antennas Well those little 1 foot jobs make decent dummy loads.

I have two on my Cornerstone. Are they both for the radio, or is one for a CB? I thought I might harvest the cable run from one for a Wilson cell booster antenna. Where do the antenna wires terminate?

At the frequency (850 MHz to 1900 MHz) that cell phones operate, the shorter the cable between antennas and radio/booster/etc. the better!! Also, the quality of the cable is very important. You might have noticed that cell tower antennas (which are high) use very large heliax type cables because big heliax minimize loss. The important issue, I think, for cell phone boosters is to have as short a cable as possible between booster and antenna. If you harvest the cable (probably RG-6), you should probably find the cable as soon as it comes through the cap and then cut it and place the booster as close to the antennas as possible (and use a cell appropriate antenna).

I think one of the antennas is for the CB and the other is for the radio. The CB wire is coiled up behind the board in the corner at the left drivers foot area. The radio antenna is connected to the back of the radio. On my coach neither works very well, but it might be the fault of the radio, not the antenna. Have to get another FM antenna and test it.

The proper length for an FM antenna is 0.75 meters,or about 29" Shorter and you loose performance (same with longer less it fits one of the other magic lengths) NOTE this is with a proper ground plane
For a CB it is about 9 feet (rounded) with ground plane
Anything shorter shortens performance.
So yes, you can replace with a stubby.. But you get stubby performance
ON my CB My antenna is about half that length, sprial wound fibererglass. It is mounted on the SIDE of the motor home
FM .. Well forget that I play CDs or other digital media on the road.

From what I have seen, all of the 2016 the CB antennas have been deleted. It's back to the old days where we installed our own antennas that worked. I have a 2014 and the antenna is about worthless. It will need to be totally re-worked to make it even receive a signal.

X2, just because they say you have a cb antenna, doesn't mean you have one!

We passed more Prevost Sunday in KY than we have ever seen in one spot. Maybe coming back from the race? Those that had CB antennas mounted were on the DS window column on a simple "L" bracket mount.

Try the radio under the outside TV. I have terrible reception on the dash radio and great reception on the one under the outside TV. I think it is just a poor radio in the dash.
