Do not use this antenna recommendation of the HBU11K antenna because it is a small size of antenna , that a small size antenna is the only size antenna that can be installed.

The reason the small HBU11K antenna is recommended for your reception situation is because the Tv Reception is Very Strong Signal Strength.
