Frequently Asked Questions
How much do I earn?
We pay 100 DKK/month via MobilePay or bank transfer. Payments are made during the first week of each month. A minimum antenna uptime applies.
What is this antenna for?
The antenna is part of a global network that improves GPS accuracy. It receives signals from satellites and/or aircraft and helps enhance positioning services.
Is this safe?
Yes. The antenna is receive-only — it does not emit any radiation. It uses between 2 and 5W depending on the model (like a small LED bulb) and very little internet bandwidth.
What do I need to provide?
A small outdoor spot (e.g., outside wall, or rooftop), power (standard 230V), and WiFi (or Ethernet).
Do I need to do anything?
No ongoing work is needed. After setup, it just needs to stay plugged into power and internet. We can support with the installation, partially or totally depending on your desired level of involvement. To avoid any risk of network disconnection, please contact us if you need to move the antenna, or change the wifi password used by the antenna.
Why are you doing this?
We’re helping expand satellite and aircraft positioning coverage in Denmark. These antennas need to be geographically spread out, and private rooftops are perfect for that.
What if I want to stop?
You can end the agreement with 30 days’ notice at any time.
Is there a referral programme?
Yes, you can earn one payment of 200 DKK for each new host that contacted us based on your referral. Conditions apply to ensure it is a valid new host.
Is there a contract?
We use a simple and clear agreement that confirms you're okay with hosting the antenna, and explains how the payment works. We'll send it to you by email once you're interested — no commitment needed.
