SALAAM
NAMASTE COVERAGE AREA FACTS:-
|
|
| 1.
The maps are drawn using engineering data from the
FCC.
2. The
coverage pattern for the station is based on the standard
ground wave field strength pattern, the frequency
of the station, and the ground conductivity of the
local area.
3. The
red, purple, and blue lines correspond to the "local",
"distant", and "fringe" coverage
areas of each radio station:
|
|
Local
Coverage (RED) : Within this area,
you will be able to receive the radio station
on almost any radio with moderately good to
very good reception.
|
|
Distant
Coverage (PURPLE) : Within this area,
the signal of the radio station is great on
a car radio or a good stereo with a good antenna.
|
|
Fringe
Coverage (BLUE) : Within this area, you
will be able to receive the reception if you
have a very good radio with a good antenna. |
|
| |
4.
The "local", "distant" and "fringe"
lines on the maps corresponds to the predicted 2.5,
0.5, and 0.15 mV/m contours respectively (of the horizontal
ground wave propagation only).
5. There
are two factors that might give our station an odd
looking coverage area: directional antenna patterns
and ground conductivity. |

FM
Antenna Patterns: 104.9 FM station has more than
one tower and hence can precisely tune it’s
antenna patterns to a very specific shape. The number
of towers, the spacing and orientation of each tower,
and the phase and ratio of the signal that is sent
to each tower all combine to create an antenna pattern
that looks heart-shaped (cardioids), peanut-shaped,
or shaped like a 3, 4, or multi-leaf clover. |
