Wireless Joint

I just purchased a Cradlepoint CBA850LP6 and have it mounted inside my motorhome. Currently I am using the 2 paddle antennas that came with it and they are working. However, I feel it could be even better with an external antenna mounted on the roof of the motorhome. Not only would I use it parked at the campground, but also I would want it to work in travel mode as well. I am looking for recommendations for a good Antenna for this application. I am using the AT&T Connected Car SIM card if that matters.

I apologize if this has already been answered but I couldn't find it.

Have never used these types of antennas, but see no reason why would not work well for your requirements:

Only one of these required:

Two of these would be required:

Since I like two antennas with separation, I would choose the second option but that is just preference. Plus like RG58U coax better:)

thewirelesshaven store seems to be closed right now, but let's hope it opens soon since many people are now working from home...

First, thank you so much for taking the time to answer my question.
I am new at all this so I still have some basic questions. Could you expand a little on why you like the 2 antennas with separation and the RG58U coax better? Also, how far should the separation be between the 2 antennas?

I also had this one recommended: https://www.amazon.com/Poynting-MIMO-3- ... 188&sr=8-6 Any thoughts?

You are very welcome!

I am ole guy with a cellular background starting in the late 80's. Basically a dinosaur, lol. The more antennas the better... Not really and lets get serious...

Without getting all technical and in laymen terms: I think two separated antennas in a mobile environment simply out perform combined antennas in one small space/package. There will be a 1000 people who disagree and some will have great/valid points (PLUS technology has come a long ways). Cellular signals in todays frequency ranges bounce around a lot and having two antennas makes better sense to ME.

With that said, there is nothing wrong with having a combined package for 4GLTE MIMO (multiple in multiple out). The one you show from Amazon is no doubt a well engineered antenna from a respected company.

As for separating distances for two antennas, I will leave that up to the manufacturer to provide. You will find 1000 opinions on the subject and best left to people selling the antenna(s). Basic rule of thumb I use is one meter apart.

There are many difference types of 50ohm coax. RG58U is a little better than RG174 when coming to signal loss. The less signal loss you have, the better performance you get. At higher cellular frequencies high loss cable is a no no. Do some research with google by typing in "coax loss cellular frequencies".

Basically what Terry is saying, is that his antenna is BIGGER than yours. lmao jk

HAHAHA, lmao!
