HexDish SignalBoost: Amplify Your Phone Signal Outdoors

HexDish SignalBoost: Amplify Your Cell Signal Outdoors
 

The SignalBoost HexDish is a modular parabolic reflector designed to enhance cell signal reception in remote areas like forests, campgrounds, or anywhere with limited coverage. Composed of interlocking hexagonal panels, the HexDish allows you to customize the size and shape of your reflector to meet your specific needs. Whether you need a compact setup or a larger dish for maximum signal capture, this flexible design has you covered.

Thanks to its lightweight and portable construction, the HexDish is perfect for outdoor use. The parabolic shape amplifies weak signals, directing them towards your device. Mount the dish to a tree, pole, or ground using its adjustable support system, and easily fine-tune the angle with the secure rosette-style fastener, ensuring optimal signal capture.

The hexagonal panels snap together with simple clips, making it easy to assemble and disassemble for storage or transport. Plus, the reflective surface is created using aluminum foil for added efficiency. The modular nature of the HexDish lets you experiment with different configurations—whether you prefer an "oval" dish, or larger dimensions, the possibilities are endless.

How it works

The operation is quite simple; it works just like a satellite dish, but instead of concentrating TV signals, it focuses on amplifying phone signals. The dish acts as a Parabolic Reflector, so radio waves that hit the surface are redirected to the focal point, amplifying the signals.

Like a satellite dish, it needs to be precisely aimed at the repeater or signal source, which can take some time to perfect. As shown in the image, the focal point isn’t always directly in front of the dish; it can be slightly offset depending on the direction of the incoming radio waves. So, try different positions or tilt the entire dish using the adjustable attachment to find the perfect spot.

Since it’s not as precise as a satellite dish, it won’t work miracles, but it can concentrate radio waves enough to provide a cellphone connection. However, in dense woods or extremely remote areas, where radio signals may be completely absent, the dish won’t be effective, as there are nothing to concentrate.
 

Use Responsibly

This device is designed to boost signal in emergencies or to let your mom know you’ve arrived safely :). It’s not intended for all-day phone use or social media. If you’re at a campsite, take the time to enjoy the experience and disconnect from digital devices ;)

Customizable Modular Sizes

The modular design means you can create a dish of various sizes:

• 37 panels for the standard design shown in the images.

• 19, 13, or 7 panels for smaller configurations.

• You can even expand beyond 37 panels.

The flexibility of the HexDish also allows you to experiment with different shapes, letting you fine-tune the dish for your specific signal needs.

Printing Instructions

• Material: PETG for outdoor durability; PLA for indoor or short-term use.

• Infill: 20% minimum, grid or rectilinear.

• Perimeters: 3 minimum for strength.

• Layer Height: 0.2 mm.

• Support: Only for adjustable arms (Organic).

• Additional Parts: Aluminum foil for the reflective surface, CA Glue (optional).

Assembly Guide

For the standard size configuration, you will need to print the following pieces:

• Hex Panel: 36 pieces
• Hex Panel with Arm Support: 1 piece
• Hex Frame: 37 pieces
• Junction Clip: 90 pieces
• Arm: 1 piece
• Fixing Bracket for Tree/Ground: 1 piece
• Fixing Bracket for Soft Ground: 1 piece (optional)
• Small Screw: 1 piece
• Big Screw: 1 piece
 

Step 1:
Print all the required files in the quantities listed above.

Step 2:
Gather the following parts: Hex Panels, Hex Frames, and the Hex Panel with Arm Support. Additionally, prepare the aluminum foil. It’s important to work on a flat surface to ensure proper panel lamination.

Step 3:
To create the reflective surface, take a Hex Frame and orient it correctly (refer to the next photo for guidance). The frame has two types of notches: one larger and one smaller. Place the smaller notch side face-down on the table.

Step 4:
Cut a piece of aluminum foil larger than the frame, then place it over the frame.

Step 5:
Position a Hex Panel over the aluminum foil. Gently press it into the frame, ensuring the panel fits slightly into the frame.
You can apply glue with a glue stick to the surface of the Hex Panel before positioning it on the aluminum foil. This will help the foil adhere better and lay flatter, preventing any unwanted detachment. You can also use two layers of aluminum foil to create a thicker reflector.

Step 6:
Once the panel is aligned with the frame, press down firmly. The panel should touch the table, and all six small notches should clip into place.

Step 7:
Fold or trim the excess aluminum foil. For added security, apply a small amount of CA glue to the corners of the frame (avoid applying glue along the sides, as it can interfere with the notches and clips).

Step 8:
Repeat these steps for all panels. One of the panels will have an arm attachment, but the assembly steps remain the same.

Tip:
To reduce aluminum foil waste, cut a strip of foil wide enough to cover three panels at once (depending on the foil’s dimensions). You can then assemble three panels together by following the steps shown in the next photos!

Step 9:
Begin assembling the modules, starting with the center piece that includes the arm support.

Step 10:
Assembling the modules is straightforward. Use a junction clip to connect two modules. Align the modules as shown in the photo, ensuring the clip fits into the corresponding notch. Make sure the two modules are perfectly aligned to prevent issues during the final assembly. Note that the sides of the frame are angled at 5°.

Step 11:
Starting from the central piece, create the first hexagonal ring using 6 panels. Clip the sides of the modules together, taking care to press on the frame’s border rather than the aluminum panel to avoid dislodging the panel.

Step 12:
Continue by assembling the second ring using the next 12 panels, following the same process.

Step 13:
Finish the assembly by adding the final 18 panels to complete the structure.

Step 14:
Attach the arm using the rosette attachment, and choose your preferred final fixing method.

Step 15:
To mount the structure on a tree using the corresponding fixing:

1. Take the final attachment and thread a rope through its holes.

2. Wrap the rope around the tree trunk and tighten it.

3. Use a tensioner (like the amazing ones linked here: "Automatic" Rope Tensioner - The only rope tensioner you will ever need V2 ) to secure the rope.

4. Attach the structure using the corresponding screws.

This fixing method can also be used on the ground by securing the structure with four metal pegs inserted through the holes.

Step 16:
If the ground is soft and free of rocks or gravel, use the alternate fixing by driving it into the ground and securing it with the corresponding screw.

Step 17:
We forgot to mention this earlier, but now you can reward yourself with at least 10 Haribo gummy bears for completing the guide! ;)

Did You Know?

Parabolic reflectors have been used for centuries to focus light and sound waves. This same principle helps boost radio and cell signals, making them a vital tool for remote communication.

Safety Information

Ensure all connections are secure and that the dish is firmly mounted to avoid accidents. Avoid setting up the dish in extreme weather conditions, as high winds could affect its stability.

Be careful in sunlight, as the aluminum foil is highly reflective. It can concentrate light in unintended spots, potentially causing an increase in temperature.
