2. ITU model for indoor attenuation - Wikipedia

   en.wikipedia.org/wiki/ITU_Model_for_Indoor...

   The ITU indoor propagation model, also known as ITU model for indoor attenuation, is a radio propagation model that estimates the path loss inside a room or a closed area inside a building delimited by walls of any form. Suitable for appliances designed for indoor use, this model approximates the total path loss an indoor link may experience.

3. Free-space path loss - Wikipedia

   en.wikipedia.org/wiki/Free-space_path_loss

   In telecommunications, the free-space path loss (FSPL) (also known as free-space loss, FSL) is the attenuation of radio energy between the feedpoints of two antennas that results from the combination of the receiving antenna's capture area plus the obstacle-free, line-of-sight (LoS) path through free space (usually air).

4. Height above average terrain - Wikipedia

   The FCC procedure to calculate HAAT is: from the proposed or actual antenna site, either 12 or 16 radials were drawn, and points at 2, 4, 6, 8, and 10 miles (16 km) radius along each radial were used. The entire radial graph could be rotated to achieve the best effect for the station.

5. Two-ray ground-reflection model - Wikipedia

   en.wikipedia.org/wiki/Two-ray_ground-reflection...

   The two-rays ground-reflection model is a multipath radio propagation model which predicts the path losses between a transmitting antenna and a receiving antenna when they are in line of sight (LOS). Generally, the two antenna each have different height. The received signal having two components, the LOS component and the reflection component ...

6. Television antenna - Wikipedia

   en.wikipedia.org/wiki/Television_antenna

   The oldest and most widely used (at least in the United States) indoor antenna is the rabbit ears or bunny ears, which are often provided with new television sets. [6] It is a simple half-wave dipole antenna used to receive the VHF television bands, consisting in the US of 54 to 88 MHz ( band I ) and 174 to 216 MHz ( band III ), with ...

7. Indoor antenna - Wikipedia

   en.wikipedia.org/wiki/Indoor_antenna

   Being close to other electric or electronic equipment in the building, an indoor antenna is prone to picking up more electrical noise that may interfere with a clear (analog) reception. [2] Used for digital broadcast, the noise is less of a factor than analog broadcast, which recently makes this type of antenna a more popular solution.
