3.How about the Warranty?

There are 12 months for the warranty.

While the warranty is not responsible for those broken by violence or updated with other brands.

4.Coverage of FM transmitter and TV transmitter.

The main parameter which decides the coverage is height of tower, so people install the antenna on very tall tower or build the tower on top of mountain. The signal has attenuation in air transmission, so people use large power of transmitter to supply the power loss. In a word, the main reason of coverage is relative height of tower to ground, secondly is power of transmitter, thirdly is antenna gain.
