In this blog post, I will instruct you on how to install a Travel 3.0 RV Max cell booster kit by HiBoost. By following this guide, you will achieve the most efficiency and use out of your new cell booster. This guide instructs you to configure the cell booster antenna onto the back access ladder and route the wiring into the cable access port box on your EKKO. This optimizes your cell booster for safe road transportation and uses the built-in cable management features designed into your EKKO by Winnebago.
Why Add a Cell Booster?
Benefits
Stronger, more reliable voice and data signal in fringe‑coverage areas
Faster upload and download speeds, improving video calls and work‑from‑road tasks
Fewer dropped calls and stalled map downloads
Works while RV is stationary and in motion
Caveats
A booster can’t create signal where none exists—at least 1 bar is required
Performance depends on the distance to (and congestion on) the nearest cell tower
Antennas (outside and interior components) may interfere with each other if not enough distance is achieved between them

Install Instructions
Step 1: Download the SignalSupervisor Mobile App
HiBoost utilizes the SignalSupervisor app, download this from your phone’s app store.
You will use the app to verify and test signals after installation.
Detailed information on the app and its capabilities can be found in the manual that comes with your kit.
Step 2: Unpackage Kit Materials and Prepare Work Area
The kit contains several small components and it is recommended that you unpackage the components and lay them out onto a flat work surface, such as a garage workbench or portable table.

Step 3: Prepare Outside RV Hardware
Take the grey waterproof putty and cut it into three segments, this will be used later in the project to secure the outside cable to the roof of your EKKO.
Assemble the outside antenna components together (poles → side exit adapter → cable spring), next assemble the antenna and outside cable together, then you will thread the 26 foot length of cable through the antenna components, and finish by screwing the entire assembly together. The assembly should like like this:

3. Take the 24-inch zip tie and a small, thin piece of blue painter’s tape and wrap them around the end of the outside cable. The intent of this funny trick is that the zip tie will be used later to guide (aka “cable fishing”) the end of the outside cable through your EKKO’s cable port box.
Step 4: Prepare Inside RV Hardware
Your kit comes with both a 120AC and 12V DC plug. It is recommended that you utilize the 12V DC plug so that your cell booster can run directly off the battery for efficiency and consistency (also, this puts less wear and tear on your inverter).
Take the booster, 12V DC plug and inside magnetic antenna and have them inside your RV for installation later on.
Step 5: Prepare the Outside Work Area
Set up your ladder and ensure it is stable.
Take all purpose cleaner and paper towels (or a microfiber cloth) and clean the top of your RV roof area and cable box (area in blue below), this is to ensure that the waterproof putty has a clean surface to adhere to.

3. Open your driver’s side over-bed cabinet compartment, inside you will find a cap in the ceiling, this is where the cable box port hole is located, take the cap off and set aside.

Step 6: Install Folding Mount Bracket, Antenna and Stabilizer Arm to Access Ladder
Install the folding mounting bracket onto the right-hand pole, two ladder rungs from the roof.
You will install utilizing the brackets, long fasteners, silicone skid pad and washers following the orientation provided in the picture below. It is advised that you loosely install all of the hardware assembly first, then orient into position for greater ease of install.
Finally, ensure that the folding mount bracket is in the downward position.
The mounting bracket should be mounted with the nuts facing inward toward the EKKO and the swivel bracket on the exterior, because this is how the antenna will be movable 180 degrees on the mount.

4. Next you will screw the antenna into the folding mount bracket.
5. Clip the stabilizer arm to the antenna pole and mount with provided zip ties onto a right-hand orientation onto the access ladder.
The stabilizer arm should be installed facing the EKKO exterior, adjust the stabilizer to sit just above the antenna head for maximum security of the hardware.
6. Your exterior antenna mount should look as followed when done:
Step 7: Thread Antenna Cable Through Cable Port Box
Start by drilling a hole directly into the middle backside of the cable port box.
Take the outside cable and route it as follows onto your roof: in front of access ladder, then behind the A/C and then toward the backside of the cable port box.

3. Ensure that the cable is not taught, it is okay for it to have a little slack. For added benefit, you may also create a small loop for extra cable length.
4. Before securing the outside cable with the waterproof putty, test the movement of your antenna in different orientations to ensure that it has enough slack.
5. Secure the outside cable with the three pieces of waterproof putty.
6. Take the end of the outside cable (which has the zip tie taped to it) and insert it into the cable port box. While one person is outside on the ladder you will want to have another person inside looking for the end of the zip tie as it is being guided through the cable port box. Be patient because this process may take some time. It helps to also have your bedroom window open so you can communicate to the person on the outside.
8. Once the person on the inside is able to retrieve the zip tie, have them slowly pull the excess cable through to the inside of the RV. It is advised that you open one of the back windows so you can easily communicate with the other person.
9. IMPORTANT! After the outside cable is threaded inside, use caulk and seal the hole that was created in the cable port box. This ensures no water penetration into your EKKO!
10. Remove the zip tie and blue table from the end of the outside cable.
Step 8: Finish Inside Hardware Install and Test Cell Booster
Connect the outside cable and inside magnetic antenna to the booster.
Plug the 12V DC plug in and insert into the booster. Optionally, you can use the 120V wall plug-in power supply, however this will mean your inverter must be turned on for you to get power to the hardware.

3. Take some time to decide where and how you will want to mount the inside hardware. Utilize the additional installation materials to help with this.
4. Open the SignalSupervisor app and follow the prompts to add and test your cell booster functionality. Detailed instructions for testing and troubleshooting are found in the kit manual.
