I'm about to return to Thailand from India and I'm considering bringing my Tatasky+ satellite receiver. My question is would it be likely that I can get a compatible dish to receive the signal. The dish is too bulky to bring.

Sat dish is available everywhere in Thailand - but have no idea if you can receive whatever satellite you are currently using - if targeted to India I doubt it.

Tata Sky

According to Lyngsat (see link), Tata Sky uses Insat 4A & G-Sat 10 at 83.0°E Ku-Band to distribute their channel package.

According to SatBeam (see link), Tata Sky uses a Ku-Band 'India beam' and Thailand is 'considered' outside of the reception 'footprint' (either because the signal is too weak. or is physically blocked by the satellite or satellite antenna design). The Tata Sky Ku-band signal is still viable along the NorthWest border of Myanmar (Burma) with a 50cm dish.

I live in Chiang Mai and I'm pretty sure on of the main pubs that's shows football has Tatasky so I'm assuming there is coverage.

When you return, you can verify with the Pub that it's a TataSky Set-Top-Box and what size Ku-band dish they're using.

All the other components you'd need to run the system, like the LNB and cabling, are standard.
