TS is highly recommended. Got my antenna 1 day after I paid.

Love it, improve my signal significantly, from 95-97db to 81-83db. The signal improves more than what TS and the antenna claim as you can actually move the antenna around to get better signal.

Download speed now is twice faster than before using the antenna. Upload speed improves even more. From 0.06Mbps-0.40Mbps to constant 1.6Mbps and above.

If you have low signal like me the antenna will definitely help.
