The " K2" beam of ST-1 covers south asia and just the western tip of Oman.
The EPIRB at OMAN is 42db. I assume you are located in Dubai.
So going further west away from the K2 footprint, you may only get about 35db
in Dubai. You may try with a 130cm or more. Its a long shot !
Frequency : 11693 H 12000 3/4
Channels : 5 Sri Lankan Channels
For alignment, you need to go about 5.5 degs to west and upward tilt as well.
Note: The K1 beam only covers a few far-eastern countries.
Location : Colombo - Sri Lanka.
