The present contribution compares mixed and horizontal polarization in various types of terrain, with particular attention to areas where reception is problematic. It is concluded that horizontal polarization is the preferred choice for use in hilly or mountainous terrain.
Login
Dear user,
Last month, the EBU switched to a new authentication method, Microsoft Entra, and decommissioned the former one (sso.ebu.ch).
What this means for most EBU Members ?
Employees of most EBU Members should now use a federated login to authenticate. This means your organization acts as the identity provider. You no longer need 2 separate accounts or 2 separate passwords. Your work credentials give you access to EBU content.
What to do on the next screen ?
If you already have an EBU account, enter your professional email address and select Next. You will see the EBU logo change to your organization’s logo. Enter your usual work password and, if prompted, accept the sharing of information with the EBU.
What if we are using shared mailboxes ?
The new authentication mechanism does not work with shared mailboxes. If you usually access EBU websites using a shared account, you must create a new individual user account. Scroll down to view the instructions.
If federated login does not work ?
For some EBU Members, as well as the general public, federated login will not work. Login remains possible with your existing account. 3 different cases may occur:
- Case 1: If your email address is linked to a Microsoft account, you will be redirected to https://login.live.com. Log in using your usual Microsoft credentials.
- Case 2: If your email address is linked to a Google account, you will be redirected to https://accounts.google.com. Log in using your usual Google credentials.
- Case 3: If your email address is not linked to either service, you will receive a temporary password by email each time you log in.
What to do if none of the above seems to work ?
Please read the instructions below carefully, as the choice you make during your first login cannot be changed later.
To create a new account, select No account? Create one.
You will have 3 options:
- Microsoft: Recommended for users working for EBU Member organizations.
- Google: Create an account using your existing Google account.
- Other valid email address: A temporary password will be sent to your inbox each time you log in.
If you still cannot log in after following these instructions, contact [email protected].
