MOON AIR Analog FM Tuner
Antenna Selection
There are two (2) antenna inputs using 75
on F-connectors located on the rear panel of the AIR, and
labelled “A1” and “A2”. You can alternate between these antenna inputs by simply pressing and
holding down the “BW 1/2” button for three (3) seconds. The default setting is “A1”. When the “A2”
antenna input is selected, “A2” indicator LED on the front panel display will illuminate. To switch back
to the “A1” antenna input, press and hold the “BW1/2” button until the “A2” indicator LED goes off.
Antenna Suggestions
The small piece of wire included should only be used as a temporary device. To obtain maximum sonic
performance from the AIR tuner, we suggest using a better quality FM antenna that can be purchased
from your dealer There are three (3) types of antennas for FM reception:
Folded dipole
This is the most common and the simplest of all antennas (like the one you receive with most
electronic gear). This piece of wire is bi-directional and the performance of it is affected by the angle
that the signal hits the piece of wire.
Vertical ½ Wave
This type of antenna offers ease of operation. The design is omni-directional which means that it picks
up stations coming from all directions. Therefore, there’s no need for a rotor. It provides 2.5dB gain to
the signal strength in comparison to a standard dipole. If excessive multipath is a common reception
problem try laying the antenna down on the horizontal plane as opposed to standing up in the vertical
plane. This type of antenna can be used both indoors and outdoors. The performance of this type of
antenna will greatly benefit from being mounted at the highest possible altitude, regardless of whether
it’s installed indoors or outdoors.
Yagi (Multi-elements)
The Yagi type of antenna is a unidirectional antenna capable of pulling in very distant stations due to
its high gain. Due to its very directional nature, it should be used with a rotor to get the maximum
benefits. The directional feature significantly helps eliminate multipath problems.
